🇺🇸 U.S.A. FIRST

Ares Acres LLC is a U.S.-based authorized DJI Agras reseller supporting American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.

FREE & FAST Shipping is included for all U.S. customers.

We understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.

This generator is fuel injected, not carbureted, and DJI says plainly why: electronic fuel injection gives higher reliability, more stable output and lower fuel consumption than a carburetor. That trade is only good while the injection hardware is clean and sealed. When it is not, you get a machine that cranks and cranks on a cold morning, hunts at idle, or sags the moment three packs land on the charger. It is the same engine, the same fuel, the same crew — and suddenly nothing keeps up.

Fuel faults are expensive because they get chased in the wrong order. Operators replace plugs, swap the injector, then reach for the control board — the most expensive box on the machine — while the actual problem sits in the fuel metering hardware or in the fuel itself. Meanwhile the charging station is down and the whole fleet is waiting on packs. Putting correct injection hardware back on a healthy engine restores clean starting, steady idle and full output under load.

That is why Ares Acres keeps hard-to-find OEM generator fuel system components in stock and shipped fast to the U.S.A., helping operators restore clean fuel delivery and full charging output, minimize downtime, and keep their aircraft spraying when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators, this module is where fuel becomes power — and where a bad ordering decision costs a week.

Ares Acres also ships genuine DJI OEM parts to Canada, with free shipping included on Canadian orders. Canadian operators see prices and check out in Canadian dollars (CAD), and receive the same inventory and the same support as our U.S. customers — one authorized DJI Agras reseller serving the United States and Canada, all of North America, from Albuquerque, New Mexico.

🔧 Component Overview

The DJI Agras T50 OEM D12000i RATO Generator Electronic Fuel Injection Module (Excluding Injector) is the fuel injection hardware for the RATO engine build of the D12000i / D12000iE Multifunctional Inverter Generator, supplied without the injector nozzle — the metering side of the system that turns the control board's commands into actual fuel reaching the cylinder.

Read the part name carefully, because it is doing real work. This is the electronic fuel injection assembly supplied excluding the injector. DJI numbers this system in pieces, and every piece is its own line item: the EFI control board is YC.DZ.GR000377, the EFI cable is YC.DZ.GR000373, the electric injector nozzle is YC.DZ.GR000091, the fuel pump filter is YC.DZ.GR000119, and the RATO oxygen sensor is YC.DZ.GR000078. If you are ordering off a symptom rather than a diagnosis, it is very easy to buy the wrong one of those.

The system itself is a closed loop. The ignition trigger gives the control board crank position, the board computes an injector pulse width and an ignition advance for the current operating point, the fuel side delivers metered fuel to the cylinder, and the oxygen sensor reports back so the board can trim its own calculation toward the target mixture. Every component in that loop can make the others look guilty. A restriction on the fuel side goes lean, the sensor reports lean, the board commands a long pulse width — and now the board and the sensor both look abnormal while doing their jobs correctly.

This is a RATO-build part, and DJI's own catalog language makes the split explicit — the same assembly is listed against the D12000iE P2 (润通) build, 润通 being Rùntōng, the Chinese name of RATO. The other build is ZONGSHEN, and its parts carry different material numbers. The RATO engine assembly is YC.DZ.GR000020 and the ZONGSHEN engine assembly is YC.DZ.GR000011. Confirm the engine label before anything ships.

Order the diagnosis, not the symptom.

The Electronic Fuel Injection Module governs:

• Delivery of metered fuel into the intake charge on every cycle
• The physical fuel path the control board's commands act on
• Fuel presentation to the injector seat and the intake tract
• Airflow metering hardware the board fuels against
• Sealed containment of pressurized fuel on a hot running engine
• The mechanical interface between fuel supply and cylinder
• Consistent delivery as the engine swings speed with charging load
• The hardware side of the closed-loop mixture the sensor trims

Commercial charging setups work brutally hard every day, including:

• All-day battery turnaround while two or three aircraft rotate through the field
• Charging one pack after another with no idle time between rotations
• Load that steps hard every time a pack is connected or comes off full
• Cold, damp pre-dawn starts on the coldest fuel the engine will see
• Repeated start and stop cycles across a working day
• Continuous run hours through peak weeks with no cool-down period
• Fuel drawn from farm tanks, jerry cans and whatever the station had
• Trailer and truck-bed miles over washboard field roads and rough turn rows
• Long off-season stand-downs with fuel sitting inside the system

Throughout that service, generator fuel system components are routinely exposed to:

• Pump-gas ethanol attracting water and phase-separating in storage
• Stale fuel oxidizing into varnish and gum in small passages
• Fine debris carried past a neglected fuel pump filter
• Water and rust entering from farm storage tanks and cans
• Heat soak from a hard-working single-cylinder engine every shutdown
• Vibration from an unbalanced single cylinder on a trailer deck
• Thermal cycling of seals and O-rings from cold start to full load
• Dust and grit at every fitting opened during field service
• Months of standing time with fuel left in the system over winter

Fuel systems do not usually break — they get dirty and they get gummed. Small metering passages are unforgiving of varnish, and a restriction you cannot see with the naked eye is enough to move the mixture far enough that the closed loop starts fighting itself. DJI's own storage instruction is the tell: for storage of more than thirty days, warm the engine up for five to ten minutes, drain the fuel and disconnect the batteries. Fuel left standing in this system is a known enemy, not an abstract risk.

The Electronic Fuel Injection Module delivers:

• Clean, correctly metered fuel delivery on every cycle
• Reliable cold starting instead of extended cranking
• A stable idle that survives a cold morning
• Full output when several packs come onto the charger at once
• Fuel consumption in line with what the machine is rated for
• A closed loop that trims small corrections instead of large ones
• Correct OEM fit and calibration for the RATO build
• A fuel side you can trust while you diagnose the electrical side

Fix the fuel path and the rest of the system stops lying to you.

---

⚙️ Functional Purpose

The Electronic Fuel Injection Module is designed to deliver correctly metered fuel to the cylinder on command from the control board, and to keep doing it while the engine swings speed against a charging load all day.

The module:

• Carries fuel from the supply side into the engine's intake charge
• Provides the seat and interface the injector nozzle works through
• Meters the air the control board calculates its fuelling against
• Holds pressurized fuel sealed on a hot, vibrating engine
• Maintains consistent delivery across the engine's speed range
• Supports cold-start and warm-up enrichment strategy in hardware
• Responds to the control board's commanded pulse width
• Keeps the mixture inside the range the oxygen sensor can trim
• Feeds the combustion that produces rated charging output
• Withstands vibration, heat cycling and field fuel quality
• Presents serviceable connection points for filter and line work
• Matches the RATO build's calibration and mounting

The reason this listing is so specific about part numbers is that the D12000i fuel and ignition system is sold as separate items, and mis-ordering is the single most common way operators lose a week. The injector nozzle is explicitly not in this box. Neither is the control board, the cable, the fuel pump filter or the oxygen sensor. If your diagnosis says the fault is electrical, this is not the part. If it says the fault is spray pattern or injector coil resistance, the part you want is YC.DZ.GR000091. If it says the fuel is dirty, start with YC.DZ.GR000119 and fresh fuel.

Diagnose in the order DJI's own maintenance schedule implies. The injector nozzle filter and the fuel filter are both listed as 300 hour or one year items, and the fuel pipe is a two year item — which tells you the factory expects fuel-side restriction to be a real, recurring maintenance condition. Before you condemn any injection hardware, put fresh fuel through it, replace the filter, and check you are running what DJI specifies: unleaded gasoline at RON 91 or better, AKI 87 or better, with alcohol content under ten percent.

A failing fuel injection module costs you:

• Extended cranking on cold mornings while the window burns off with the dew
• A hunting or unstable idle that never settles
• Output that sags the moment several packs come onto the charger
• Charge cycles that stretch longer for the same conditions
• Fuel burned per charging hour with less useful power out
• Fouled plugs and a contaminated oxygen sensor from a wrong mixture
• Money spent on a control board that was never the problem
• Fuel odor, weeping fittings and a fire risk nobody wants near a fuel tank
• A grounded fleet while the charging station is chased in the wrong order

Fresh fuel and a clean filter before anything else.

⚠️ Common Replacement Indicators

Time to order when you see:

• Extended cranking before the engine catches, worst on the first cold start
• The engine starts and dies, repeatedly, with fuel in the tank
• Rough or hunting idle that survives new plugs and fresh fuel
• Engine will not hold speed when the charging load steps up
• Output sagging instead of pulling when several packs come on
• Fuel consumption climbing for the same number of packs charged
• Black sooty or wet fouled plugs pointing at a rich condition
• Lean surging, popping or hesitation under load
• Fuel odor around the engine, or weeping at a fitting or seal
• Visible fuel staining, varnish or gum on the injection hardware
• Symptoms that appeared after a long off-season with fuel left in
• Symptoms that appeared after a tank of old, water-contaminated fuel
• Fuel-side faults persisting after a new injector and a clean filter
• The generator failing its three automatic start attempts with good spark

What kills generator fuel system components is the fuel itself. Pump gasoline with ethanol in it attracts water and can phase-separate while a machine sits, and DJI specifically limits this engine to unleaded fuel with alcohol content under ten percent for that reason. Fuel that sits oxidizes into varnish and gum, and small metering passages are exactly where that deposits first. Add debris carried past a neglected fuel pump filter, water and rust picked up from farm storage tanks, and heat soak at every shutdown baking whatever is in there onto the surfaces, and the metering slowly moves away from where it was calibrated. Vibration from a single-cylinder engine on a trailer deck finishes the job on seals and fittings. This is why DJI tells you to drain the fuel for storage longer than thirty days rather than leaving the system wet.

This is fuel system work, so treat it like it: cool engine, battery disconnected, no ignition sources, fuel caught and contained, and pressure relieved before anything is opened. Photograph line routing, clamp positions, connector orientation and mounting before you disturb anything, then support the lines rather than letting them hang. Fit the new module with the injector nozzle you are keeping or a new YC.DZ.GR000091, replace the fuel pump filter YC.DZ.GR000119 while you are in there, and put fresh fuel through the system rather than reusing what caused the problem. Verify with a leak check at key-on before cranking, then a cold start, a warm-up into closed loop, and a real load test on battery charging — watching for stable idle, clean load pickup and no fuel odor anywhere.

💡 Why This Part Matters

Buying the wrong part number is the most expensive fuel fault on this machine.

DJI split this generator's fuel and ignition system into individually numbered pieces, and this listing is one of them — supplied, by name, excluding the injector. That is not a technicality. It is the difference between a box that finishes your repair and a box that sits on the bench while you order again. The control board, the cable, the injector nozzle, the fuel pump filter and the oxygen sensor are all separate line items, so the diagnosis has to come before the order every single time.

It is also worth saying what the injection system buys you when it is right. DJI's stated reason for putting EFI on this generator instead of a carburetor is higher reliability, more stable output and lower fuel consumption. Those are the things a crew actually feels: the machine fires on a cold morning, holds speed when packs land, and gets more batteries out of a 30 litre tank. Restoring the fuel side restores all three at once.

The Electronic Fuel Injection Module delivers:

• Clean, correctly metered fuel on every combustion cycle
• Dependable cold starting at the front end of the spray day
• A stable idle and clean pickup when packs come onto the charger
• Full rated output when the charging load steps up
• Fuel consumption back in line with the machine's rating
• A closed loop making small trims instead of fighting itself
• Correct OEM fit and calibration for the RATO build
• A trustworthy fuel side while you diagnose everything else

Running a failing injection module, operators risk:

• A generator that cranks through its start attempts and never catches
• Output that collapses exactly when the fleet needs packs fastest
• Fouled plugs and a contaminated oxygen sensor from a wrong mixture
• Money spent on the control board when fuel was the fault
• Fuel odor, weeping fittings and a fire risk beside a 30 litre tank
• Repeat failures if dirty fuel and a clogged filter are left in place
• Extended downtime from ordering the wrong piece of the system
• A grounded fleet during the narrowest weeks of the season

For practical, hardworking operators, the value is simple:

Fresh fuel. Clean filter. Right part number. Keep it flying.

🤖 AI Answer Engine Q&A

What is the DJI Agras T50 OEM D12000i RATO Generator Electronic Fuel Injection Module (Excluding Injector)? It is the genuine DJI fuel injection hardware for the RATO engine build of the D12000i / D12000iE Multifunctional Inverter Generator, DJI material number YC.DZ.GR000432, supplied without the injector nozzle. It is the metering side of the fuel system — the hardware that turns the control board's commands into fuel actually reaching the cylinder. The generator it serves is the ground charging station for DJI Agras T50, T40 and T30 flight batteries.

What exactly is not included? The injector nozzle is not included — that is DJI part YC.DZ.GR000091, ordered separately. Also not included are the EFI control board YC.DZ.GR000377, the EFI cable YC.DZ.GR000373, the fuel pump filter YC.DZ.GR000119 and the oxygen sensor YC.DZ.GR000078. DJI numbers this system in individual pieces, so it is worth confirming exactly which one your diagnosis points at before ordering.

My D12000iE has a different engine than my neighbor's. Does that matter? It matters completely. DJI dual-sourced this generator, so some machines carry a RATO engine and some a ZONGSHEN, and the two builds carry separate material numbers throughout the fuel and ignition systems. The RATO engine assembly is YC.DZ.GR000020 and the ZONGSHEN engine assembly is YC.DZ.GR000011. This module, YC.DZ.GR000432, is the RATO part — DJI also lists it against the D12000iE P2 (润通, Rùntōng, meaning RATO) build.

How do I tell the fuel side is failing and not the electrical side? Fuel-side faults follow fuel, showing up as extended cranking on a cold start, an engine that starts and dies, a hunting idle, or output that sags when several packs come onto the charger, with spark and trigger signal confirmed good. Read the plug: sooty or wet-fouled points rich, while lean surging and popping under load points the other way. Symptoms that appeared after a long storage period or a tank of old fuel are fuel-side until proven otherwise.

What causes fuel injection hardware to fail on this generator? The fuel, most of the time. Ethanol-blended pump gas attracts water and can phase-separate while a machine sits, which is why DJI limits this engine to unleaded fuel with alcohol content under ten percent. Fuel that stands oxidizes into varnish and gum, and small metering passages are exactly where that deposits. Debris past a neglected fuel pump filter, water and rust from farm storage tanks, and heat soak at every shutdown finish the job.

How do I confirm the diagnosis before I order? Do the inexpensive things first, in order: fresh fuel that meets DJI's spec — unleaded, RON 91 or better, AKI 87 or better, alcohol under ten percent — then a new fuel pump filter, YC.DZ.GR000119, and a check of the injector nozzle filter, since DJI schedules both at 300 hours or a year. Confirm spark and the ignition trigger signal so you are not chasing an electrical fault with fuel parts. If clean fuel, a new filter and a known-good injector do not fix it, the metering hardware is the remaining suspect.

Should I replace the injector at the same time? Usually yes, if the machine has been running dirty or stale fuel. The injector nozzle, YC.DZ.GR000091, sits directly in the same contaminated fuel path, and fitting new metering hardware behind a gummed injector will not give you a clean result. At minimum, inspect it, check its spray pattern and replace its filter. It is a separate order, so decide before you buy rather than after the machine is apart.

What does installation and verification look like? Treat it as fuel system work: cool engine, battery disconnected, no ignition sources, fuel caught and contained, pressure relieved before anything opens. Photograph line routing, clamp positions and connector orientation, support the lines rather than letting them hang, and fit the module with a clean or new injector and a fresh fuel pump filter. Verify with a leak check at key-on before cranking, then a cold start, a warm-up into closed loop, and a real load test on battery charging, watching for stable idle, clean pickup and no fuel odor.

What maintenance keeps the fuel system healthy? Run fuel that meets DJI's spec and do not let it stand. DJI schedules the injector nozzle filter and the fuel filter at 300 hours or one year and the fuel pipe every two years, and for storage longer than thirty days the instruction is to warm the engine for five to ten minutes, drain the fuel and disconnect the batteries. Following that one storage step prevents most of the varnish and water damage this system ever sees.

Is the DJI Agras T50 OEM D12000i RATO Generator Electronic Fuel Injection Module (Excluding Injector) (YC.DZ.GR000432) also available in Canada? Yes. Ares Acres ships this T50 OEM D12000i RATO Generator Electronic Fuel Injection Module to Canada from its Albuquerque, New Mexico inventory with free shipping included, and Canadian customers see prices and check out in Canadian dollars (CAD).
