ARCO Johnson/Evinrude Fuel Pumps: FP001, FP002, FP003 & FP004

Johnson and Evinrude outboards can use different mechanical fuel pumps even when the engine horsepower looks the same. The ARCO FP001, FP002, FP003 and FP004 replacement assemblies are distinct part numbers. Use the original pump number and your engine's full model identification to find the right one.

Choose by engine family, then verify the original number

ARCO fuel pump reference chart

The engine ranges and replacement numbers below are drawn from ARCO's individual FP-series product information. An engine can fall within a general range yet use a different pump: use the model-specific parts diagram to establish the correct original pump number.

Check these details before changing a fuel pump

1. Locate the outboard model and serial number, then identify the original pump assembly in its parts reference.
2. Compare the original OMC part number with the cross-reference for the specific ARCO MPN.
3. Inspect the mounting position and the direction of the fuel inlet and outlet. The store listings identify hose-barb inlet and outlet connections for these models; check the physical arrangement before fitting.
4. Use fuel-rated hoses, clamps and other parts specified for the engine. Do not assume a primer bulb, fuel hose or gasket is included unless the individual listing confirms it.
5. Work on a cool engine, keep ignition sources away from gasoline, and verify connections are leak-free using the manufacturer's service procedure before operation.

Questions when identifying an OMC replacement pump

Will FP001 fit every Johnson/Evinrude 10–55 HP outboard? No. The manufacturer gives that as one application family, not an all-model interchange guarantee. Cylinder count and the original assembly number still matter.

Is FP004 interchangeable with FP001 because both mention 20–35 HP? No. They have different ARCO and OEM cross-references. Match the engine's parts list instead of choosing by horsepower.

Does a new fuel pump fix every fuel-delivery problem? No. A damaged hose, blocked filter, faulty connector or fuel-tank vent can produce other fuel-flow symptoms; identify the cause before replacing parts.

If the fuel line or filter is also being serviced, see our marine fuel-line and primer-bulb guide and inline fuel-filter identification page. Those accessories have their own compatibility requirements and are not interchangeable with the fuel pump.
