Installation notes
Completely dismantle the fuel pump and inspect all components before fitting the new parts. Replace all gaskets and sealing rings from the kit. Ensure correct fitting direction of the diaphragm and proper operation of the valves. Test the pump after assembly for correct pressure (2.5-3.75 psi for early models).
Compatibility
Suitable for original mechanical fuel pumps on vehicles with L-134 engine. Different pump models were used over the years — verify your pump type before ordering. Not suitable for dual-action pumps with vacuum section (which require additional parts). Diaphragms from old stock may have hardened — always use new diaphragms compatible with modern fuels.
Historical context
The mechanical fuel pump of the WWII jeep was driven by an eccentric on the camshaft and delivered fuel under low pressure to the carburettor. This reliable design remained in service for decades on civilian Willys jeeps.
