Why the Same Fuel Pump Number Ships in Multiple Variants

The base number alone does not guarantee fitment — port orientation, connector style, and pressure rating differ across production runs.

I have stood on job sites in Southeast Asia watching a utility vehicle sit idle because the replacement fuel pump arrived with ports rotated to the wrong clock position. The part number matched the service manual exactly. The machine was a John Deere Gator 4X2 from a later serial range, and the pump variant needed for that serial bracket had a port layout rotated from the earlier production version. Copied cross-reference tables between sellers carry these errors forward, and by the time the unit arrives on site, the machine has been down for days [NEED_CITE: fuel pump variant differences across utility vehicle serial ranges]. A 12V Electric Fuel Pump AM876265 for John Deere Gator cross reference fitment verification starts with serial range confirmation, not just a catalog number lookup.

Machine Model and Serial Range Coverage

This fuel pump is compatible with a broad range of John Deere utility vehicles and the engine platforms that power them. The fitment list spans the Gator 4X2, 4X4, and 6X4 series, HPX variants, ProGator models, Trail and Worksite Gators, and the 322 compact tractor. Beyond the machine badges, the pump also fits standalone Kawasaki FD620D and FD750D engines as well as the Yanmar 3TG72. The key to correct selection is matching the machine serial prefix and engine build date against the known variant breakpoints, since the same model name can span two or three distinct fuel system configurations.

Port Orientation and Interface Verification

Before confirming an order, the critical checks are port thread specification, port clock position, and electrical connector type. This pump uses SAE J1926-1 metric M12×1.25 port threads, which must match the existing fuel line fittings on the machine. Port clock position — the angular relationship between the inlet and outlet ports relative to the mounting face — varies between early and late production units within the same model line. The electrical connector should be verified against the existing harness plug, since pin count and housing shape changed across certain Gator serial breakpoints [NEED_CITE: SAE J1926-1 metric port thread standards for small engine fuel systems]. Providing a photograph of the old pump's port face and connector alongside the machine serial number allows precise variant confirmation before anything ships.

Pressure Rating and Internal Construction

The operating pressure band of 3.5–4.2 psi places this pump squarely within the low-pressure electric fuel delivery range typical of carbureted small engines. Exceeding this range risks flooding the carburetor float bowl, while falling short causes lean running and hesitation under load. The A380 aluminum alloy housing provides corrosion resistance in environments where fuel moisture and outdoor storage are routine. Internally, silver-graphite composite brushes offer stable electrical contact across the -20°C to +85°C operating temperature range, which matters for machines that start cold in high-altitude mining sites and run through midday heat on agricultural fields. Shaft runout held to ≤0.03 mm TIR ensures consistent brush wear and prevents the premature commutator scoring that causes intermittent fuel delivery.

What Happens When the Wrong Variant Gets Forced Onto the Machine

A fuel pump that physically bolts up but has incorrect port clocking forces the installer to bend or reroute fuel lines, creating restriction points that starve the engine under load. A pump with mismatched pressure output may run the machine at idle but fail when the operator demands full throttle on a grade. I have seen cases where a slightly wrong variant was installed and the machine ran for a few hours before the carburetor flooded, washing oil off the cylinder walls and scoring the bore. The cost of the wrong pump is never just the return freight — it is the downstream engine damage and the second round of downtime while the correct part is identified and sourced [NEED_CITE: carburetor flooding consequences from incorrect fuel pump pressure in small engines].

Why Sourcing This Part Here Reduces Fitment Risk

Our own production lines and qualified sourced supply operate under a single QC protocol and carry the same warranty terms, so there is no quality gap between in-house and partner-sourced fuel pumps. Eight product categories under one account mean that if the repair also calls for fuel filters, seal kits, or electrical connectors, everything ships as one consignment rather than arriving from separate suppliers on different dates. Orders start from one piece, so a single emergency replacement does not require a minimum batch commitment. Identification is possible from the part number, machine model, a photograph of the nameplate, or even a painted-over data plate — the technical team cross-references serial range against variant breakpoints. A sample unit is available for physical fitment trial before any bulk commitment, which removes the guesswork for distributors stocking multiple Gator variants.

Documentation & Verification

• Commercial invoice and packing list with part number and variant code noted
• Cross-reference sheet mapping AM876265, AM109405, and AM876023 with serial range applicability (reference only)
• Dimensional check record covering port spacing, thread verification, and shaft runout measurement
• Warranty terms covering manufacturing defects for 3 to 12 months from dispatch
• Packing photographs showing port protection caps and anti-corrosion wrapping before crating
• HS code and customs documentation support for fuel system component export classification

Fitment Check Before Installation

• Compare port clock position on the new pump against the removed unit before connecting fuel lines
• Verify M12×1.25 thread engagement with existing fittings — do not force mismatched thread standards
• Check electrical connector pin count and housing shape against the machine harness plug
• Confirm mounting bolt pattern alignment with the bracket before tightening to avoid housing stress
• Run the pump briefly with fuel line disconnected at the carburetor to verify flow direction and pressure
• If port orientation or connector does not match, stop installation and contact us with photographs for exchange

Send Your Machine Details for Fitment Confirmation

To verify which variant fits your equipment, provide the machine model, serial number or serial prefix, and a photograph of the existing pump showing the port face and electrical connector. If the nameplate is worn or painted over, a clear image of the engine data plate or the machine chassis tag is sufficient for identification. This information allows the technical team to cross-reference the correct variant and confirm compatibility before any order is placed.

Frequently Asked Questions

Q: How do I confirm this pump fits my specific Gator or 322 variant? A: Provide the machine model and serial number prefix. We cross-reference the serial range against known variant breakpoints for port orientation, connector type, and pressure rating. If the nameplate is unreadable, a photograph of the existing pump's port face and connector is enough to confirm fitment before shipping.

Q: My current part number is AM109405 or AM876023 — does this pump still work? A: These numbers are listed as cross-reference identifiers (reference only) for the AM876265 fuel pump. In most cases they represent superseded or alternate numbers for the same application, but variant differences can exist across serial ranges. Send us the number along with your machine serial so we can verify the correct match.

Q: Why do I see different fuel pump variants listed under the same base number? A: Production changes across model years can alter port clock position, electrical connector style, or pressure calibration while retaining the same base part number. Copied cross-reference tables often fail to capture these variant breakpoints. We verify against serial range data rather than relying on catalog listings alone.

Q: I only have the machine model with no readable part number — can you identify it? A: Yes. The machine model combined with a serial prefix or production year range is sufficient for identification. If neither is available, a photograph of the engine compartment showing the fuel system layout and existing pump mounting position allows our technical team to narrow down the correct variant.

Q: Can I order a sample to test fitment before committing to a larger quantity? A: Sample units are available for physical fitment confirmation. Install the sample on the target machine, verify port orientation, connector match, and operational pressure, then confirm the bulk order once fitment is proven. This approach eliminates the risk of stocking the wrong variant across a mixed fleet.
