Walbro 2401 Fuel Pump Cross Reference
The pump most commonly referred to as the 2401 has been a bedrock for the entire Walbro carburetor fuel pump family. It replaced the Walbro WEP12 fuel pump, and has since been replaced by the Walbro FRA-1 Fuel Pump and FRD-1 Fuel Pump.
Please take careful note to what this is and what it is not. This is the result of hours of research, digging through outdated manuals and cross-referencing fuel pumps that were discontinued years ago to help fast-forward you in your search for a replacement. It is not guaranteed to be perfect, and it is not a promise that the new FR-series fuel pump will drop into place with no additional effort--although I believe that will be the case most of the time.
All of these fuel pumps for carbureted applications:
Can be replaced by either of these two fuel pumps:
A Few Notes:
-Don't see your fuel pump in the list above? Check the Walbro 2402 Fuel Pump Cross Reference or Jump to the main Walbro FR-Series Fuel Pump Page to make your selection based on fuel pump specifications.
-Either of the FR-series fuel pumps are an excellent choice for carbureted vehicles with an OE electric fuel pump. Similarly, if you want to replace your mechanical fuel pump in your carbureted car this is a good choice (vehicles up to about 200 HP.)
-Although an NSN number (military application) is listed above, the new FR-series pumps have not been DOD-approved as a replacement. Use your own judgement about suitability.
