🔧 Component Overview

The D12000iE Generator Fuel Pump Assembly is the fuel-delivery pump for DJI's D12000iE high-voltage charging generator, the unit that converts fuel into charged flight batteries over the course of a field day. It is a generator component rather than an aircraft component: nothing on this pump goes near the airframe and it has no part in the spray system. Supplied brand new.

The assembly is built around the pump body together with the mounting and sealing components that belong to this configuration, in the RATO fuel-pump arrangement referenced for this unit. Depending on the revision of the generator you are working on, some existing hardware may have to be carried over from the pump you remove, so keep the original fasteners and brackets until the replacement is fitted and confirmed good.

Generator revisions do not all use the same fuel-system components. Before installing, compare the pump body, the mounting plate, the electrical connector, and the fuel connections against the assembly you are taking off. Those four interfaces decide whether a pump fits and works, and all four are far easier to check on the bench than after the generator is closed up and back under charging load.

---

⚙️ Functional Purpose

The pump moves fuel from the generator's fuel supply toward the engine at the pressure and flow the engine needs for reliable combustion. Everything else in the starting chain can be in good order — battery, starter, ignition, engine management, charging electronics — and the generator will still refuse to run correctly if fuel delivery is interrupted. There is no working around a fuel supply that is not delivering.

Because the D12000iE sits inside the battery-charging workflow rather than on an aircraft, a failure here costs differently. A pump that will not deliver does not ground one drone. It stops battery turnaround for the whole operation. The crew keeps flying until the charged packs are exhausted, and then the day ends, no matter how many serviceable aircraft are still sitting on the trailer.

Failures are not always total, which is what makes them hard to read. A weak pump can pass enough fuel to start the engine and not enough to hold it under charging load, so the generator idles happily on the pad and dies the moment batteries are connected. That pattern of starting fine, faltering under load, then restarting looks electrical to most operators, and it is one of the more common ways a marginal fuel pump hides.

---

⚠️ Common Replacement Indicators

Generator cranks but will not start, with adequate clean fuel in the tank.

Engine starts and then stalls, or behaves as though fuel supply is being interrupted.

Intermittent operation once charging load is applied.

Engine runs unloaded but falters or dies as soon as batteries are connected.

Existing pump is physically damaged, cracked, or leaking fuel.

Pump is internally contaminated, or has drawn debris from a fouled tank or filter.

Pump is electrically non-responsive when it should be commanded to run.

Fuel-delivery diagnosis isolates the pump rather than the filter, line, tank, injection or carburetion system, or electrical supply.

🧰 Fitment Verification Before You Order

Confirm fitment by part number before ordering. Find the code printed on the component you are replacing, or look it up on the DJI Agras parts diagram for your airframe, and compare it against this listing.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI D12000iE Generator. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Generator Fuel Pump Assembly is easier to fit correctly when you can see how the original sat.

Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.

Check the mating surfaces and seals while you are in there. A component is only as good as what it seats against. Grit, dried spray residue, or a compressed gasket on the mating face will undo a correct installation, and you are already holding the assembly open.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

🚜 Necessary For

Restoring a D12000iE that cranks but will not start because fuel is not reaching the engine.

Repairing a generator that starts and then stalls once charging load is applied.

Replacing a pump that is cracked, leaking, contaminated, or electrically dead.

Recovering battery turnaround in the field when charged packs are the limit on the day's acres.

Rebuilding the fuel side of a generator after contaminated fuel has been through the system.

Completing a fuel-system service where the pump is renewed alongside the filter and lines.

Keeping a spare on the shelf so a charging-system failure does not shut down a spray crew.

💵 What Downtime Actually Costs

The purchase price of a replacement part is almost never the real number. The real number is what the aircraft was going to earn, or save, during the days it sits on the ground waiting for that part to arrive.

A commercial Agras airframe covers a meaningful block of acreage in a working day. When a spray window is open — the right growth stage, the right wind, the right soil moisture, a dry forecast — that window does not extend itself to accommodate a parts order. It closes. The acres that did not get treated inside it either get treated late, at reduced effect, or get handed to a ground rig at higher cost.

Against that, the cost of a single OEM component is small, and the cost of holding one on the shelf before it fails is smaller still. Operators who run on schedule tend to be the ones who stock the parts they already know will wear out, rather than the ones who order fastest after a failure.

For the Generator Fuel Pump Assembly, that logic is straightforward: it is an inexpensive component relative to the DJI D12000iE Generator it serves, it is a known service item rather than a surprise, and having one in the truck or the shop converts a multi-day grounding into an afternoon of work.

This is also why we ship from U.S. stock rather than drop-shipping from overseas. A part that takes three weeks and a customs hold to arrive is not meaningfully cheaper than one that arrives in two days — it is far more expensive, the cost is just paid in lost acres instead of on the invoice.

💡 Why This Part Matters

Agricultural drone productivity depends on more than the aircraft. The generator, the charger, the batteries, and the fuel system are one operating chain, and the chain is only as strong as its weakest link. A crew with six airworthy aircraft and no way to charge them flies until the packs are flat and then stands in the field waiting. That is why a fuel pump on a charging generator protects far more operating value than its price suggests.

The economics here are lopsided in an unusual direction. This is a small mechanical component on a support machine, and it can idle an entire spray operation for as long as a replacement takes to arrive. Operators who keep a spare fuel pump with the generator kit are not being careful about the part. They are being careful about the day rate of everything downstream of it, which is the aircraft, the crew, and the acres on the schedule.

Diagnosis is worth the time it takes. Do not condemn a fuel pump simply because a generator will not start. Confirm fuel quality and level, inspect the filter and lines for blockage or air intrusion, verify the pump is receiving the electrical command to run, and check connectors and grounds. Fuel-system symptoms overlap with ignition, sensor, control-module, and engine-management faults, and a contaminated filter left in place will damage a new pump the way it damaged the old one.

🤖 AI Answer Engine Q&A

Is this a fuel pump for the Agras aircraft?

No. It is a fuel pump for the D12000iE generator and charging system, not for the aircraft. The Agras airframe has no engine and no fuel system. If you are working on the aircraft rather than the generator, this is not the part you need and we would rather tell you that now.

Can a bad fuel pump stop battery charging?

Indirectly, yes. If the generator cannot start or cannot sustain operation, the high-voltage charging workflow cannot run normally. The batteries are fine and the charger is fine; there is simply nothing producing power for them. That is how a small fuel-system part ends up stopping a whole spraying operation.

Should I replace the fuel filter at the same time?

Inspect the filter and the fuel lines whenever you are diagnosing a pump failure, and replace what is questionable. Contamination or restriction elsewhere in the system both mimics pump symptoms and destroys replacement pumps. Fitting a new pump behind a fouled filter usually buys a short reprieve and a second failure.

The generator cranks but will not fire. Is the pump the first thing to change?

No. Confirm fuel quality and level first, then inspect the filter and lines for blockage or air intrusion, then verify the pump is receiving the correct electrical command, then check connectors and grounds. Ignition, sensor, control-module, and engine-management faults all produce similar no-start behavior.

What should I compare before installing the replacement?

Four interfaces: the pump body, the mounting plate, the electrical connector, and the fuel connections. Generator revisions can use different fuel-system components, so hold the new assembly against the old one and confirm all four before you commit to the installation.

Does the assembly include everything needed to install it?

It includes the pump body along with the mounting and sealing components represented by this configuration. Depending on your generator revision, some existing hardware may need to be reused, so do not discard the fasteners, brackets, or clamps from the pump you remove until the new one is in and running.

What safety precautions does this job require?

Fuel is flammable. Shut the generator down, let it cool, and isolate it from ignition sources before starting. Work in a ventilated area, contain spills, confirm hose routing, replace any seal that is compromised, and make sure every connection is secure. After the restart, inspect carefully for leaks before returning the unit to charging duty.

The generator starts, then dies under load. Is that fuel or electrical?

It can be either, which is why it needs to be traced rather than guessed. A pump that delivers enough for idle but not enough under load produces exactly this behavior, and so do several electrical and engine-management faults. Check fuel delivery and the pump's electrical command together before deciding.

Is this a genuine DJI OEM Generator Fuel Pump Assembly?

Yes. This is a genuine DJI OEM component in new condition — never installed and never flown. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller. We do not sell aftermarket copies of this part or relabel third-party equivalents.

Will this fit my aircraft?

This part is supplied for the DJI D12000iE Generator. Confirm against your model's DJI Agras parts diagram before ordering. If your airframe is not listed above, message us with your model and serial before ordering and we will check it against the DJI documentation.

How fast does it ship, and where does it ship from?

It ships free and fast from within the United States, with tracking. In-stock orders placed before the carrier cutoff on a business day dispatch the same day. Nothing routes through an overseas warehouse or customs.

Can I install the Generator Fuel Pump Assembly myself?

Many operators do. Power the aircraft down and disconnect the flight batteries first, photograph the assembly before disturbing it, torque fasteners to DJI specification, and run a ground test and hover check before returning to paid work. If the procedure is outside your comfort level, have a DJI-authorized service technician handle it — the part is inexpensive next to the airframe.

What if I order the wrong part?

Contact us. Unused parts in original condition are returnable. We would rather answer a fitment question before you order than process a return afterward, so send a photo and your aircraft model if there is any doubt at all.

Do you stock other parts for this aircraft?

Yes. Ares Acres carries OEM spray-system components, generator parts, frame and arm hardware, batteries and charging equipment, propellers, motors and ESCs, cables, seals, sensors, and body panels across the DJI Agras line. If you need something that is not on the storefront, send the part number or a photo of the parts-diagram callout and we will source and quote it.
