That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003cp\u003eFuel 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.\u003c\/p\u003e\n\u003cp\u003eThat 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.\u003c\/p\u003e\n\u003cp\u003eFor professional farmers, aerial applicators, and commercial drone operators, this module is where fuel becomes power — and where a bad ordering decision costs a week.\u003c\/p\u003e\n\n\n\u003chr\u003e\n\u003ch2\u003e✅ DJI Agras T50 \/ T40 \/ T30 Compatibility Guarantee\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e🇺🇸 USA Compatibility Guarantee\u003c\/li\u003e\n\u003cli\u003e👍🏻 Satisfaction Guarantee\u003c\/li\u003e\n\u003cli\u003e💵 Money Back Guarantee\u003c\/li\u003e\n\u003cli\u003e📦 Same Day Shipping \u0026amp; Tracking\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\n\u003chr\u003e\n\u003ch2\u003e📦 Package Includes\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 × OEM Electronic Fuel Injection Module (YC.DZ.GR000432)\u003c\/li\u003e\n\u003cli\u003eOEM electronic fuel injection module for the RATO engine build of the D12000i generator\u003c\/li\u003e\n\u003cli\u003eSupplied EXCLUDING the injector nozzle — that is DJI part YC.DZ.GR000091, ordered separately\u003c\/li\u003e\n\u003cli\u003eNot included: EFI control board YC.DZ.GR000377, EFI cable YC.DZ.GR000373, fuel pump filter YC.DZ.GR000119, oxygen sensor YC.DZ.GR000078\u003c\/li\u003e\n\u003cli\u003eContact us with your engine label before ordering if you are unsure which pieces you need\u003c\/li\u003e\n\u003cli\u003eOEM protective packaging\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\n\u003chr\u003e\n\u003ch2\u003e🔧 Component Overview\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003eDJI Agras T50 OEM D12000i RATO Generator Electronic Fuel Injection Module (Excluding Injector)\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003eRead 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThis 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.

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.

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.

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.\u003c\/p\u003e\n\u003cp\u003eA failing fuel injection module costs you:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eExtended cranking on cold mornings while the window burns off with the dew\u003c\/li\u003e\n\u003cli\u003eA hunting or unstable idle that never settles\u003c\/li\u003e\n\u003cli\u003eOutput that sags the moment several packs come onto the charger\u003c\/li\u003e\n\u003cli\u003eCharge cycles that stretch longer for the same conditions\u003c\/li\u003e\n\u003cli\u003eFuel burned per charging hour with less useful power out\u003c\/li\u003e\n\u003cli\u003eFouled plugs and a contaminated oxygen sensor from a wrong mixture\u003c\/li\u003e\n\u003cli\u003eMoney spent on a control board that was never the problem\u003c\/li\u003e\n\u003cli\u003eFuel odor, weeping fittings and a fire risk nobody wants near a fuel tank\u003c\/li\u003e\n\u003cli\u003eA grounded fleet while the charging station is chased in the wrong order\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFresh fuel and a clean filter before anything else.\u003c\/p\u003e\n\n\n\u003chr\u003e\n\u003ch2\u003e⚠️ Common Replacement Indicators\u003c\/h2\u003e\n\u003cp\u003eTime to order when you see:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eExtended cranking before the engine catches, worst on the first cold start\u003c\/li\u003e\n\u003cli\u003eThe engine starts and dies, repeatedly, with fuel in the tank\u003c\/li\u003e\n\u003cli\u003eRough or hunting idle that survives new plugs and fresh fuel\u003c\/li\u003e\n\u003cli\u003eEngine will not hold speed when the charging load steps up\u003c\/li\u003e\n\u003cli\u003eOutput sagging instead of pulling when several packs come on\u003c\/li\u003e\n\u003cli\u003eFuel consumption climbing for the same number of packs charged\u003c\/li\u003e\n\u003cli\u003eBlack sooty or wet fouled plugs pointing at a rich condition\u003c\/li\u003e\n\u003cli\u003eLean surging, popping or hesitation under load\u003c\/li\u003e\n\u003cli\u003eFuel odor around the engine, or weeping at a fitting or seal\u003c\/li\u003e\n\u003cli\u003eVisible fuel staining, varnish or gum on the injection hardware\u003c\/li\u003e\n\u003cli\u003eSymptoms that appeared after a long off-season with fuel left in\u003c\/li\u003e\n\u003cli\u003eSymptoms that appeared after a tank of old, water-contaminated fuel\u003c\/li\u003e\n\u003cli\u003eFuel-side faults persisting after a new injector and a clean filter\u003c\/li\u003e\n\u003cli\u003eThe generator failing its three automatic start attempts with good spark\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhat 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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\n\n\u003chr\u003e\n\u003ch2\u003e📐 Specifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDJI Material Number:\u003c\/strong\u003e

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.\u003c\/p\u003e\n\u003cp\u003eIt 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.

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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat exactly is not included?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMy D12000iE has a different engine than my neighbor's. Does that matter?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I tell the fuel side is failing and not the electrical side?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat causes fuel injection hardware to fail on this generator?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I confirm the diagnosis before I order?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I replace the injector at the same time?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does installation and verification look like?\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat maintenance keeps the fuel system healthy?\u003c\/strong\u003e 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.
