Installation Notes

Disconnect the negative battery terminal and relieve all pressure from the fuel system.
Carefully access and remove the Vapor Separator Tank (VST) assembly from the engine.
Disconnect the fuel lines and electrical connectors from the old fuel pump.
Remove the old pump, noting its orientation and the position of any rubber grommets or mounts.
Clean the VST interior of any debris or sediment before installing the new pump.
Install the new fuel pump, ensuring all seals and mounts are correctly seated.
Securely reconnect the electrical spade terminals and fuel lines.
Reinstall the VST assembly, prime the fuel system according to the engine service manual, and check for leaks before starting.

Troubleshooting & FAQ

How do I know if my fuel pump is failing?

Common signs include the engine bogging down at high speeds, difficulty starting, sputtering, intermittent power loss, or a complete failure to start. A fuel pressure test can definitively confirm if the pump is operating below the required specification for your engine.

Is this a high-pressure or low-pressure pump?

This is a high-pressure electric fuel pump designed specifically for Electronic Fuel Injection (EFI) systems, which require significantly higher fuel pressure than older carbureted engines.

What is required for proper installation?

It is critical to install a new fuel filter and thoroughly clean the VST tank to prevent debris from damaging the new pump. Ensure all electrical connections are secure and fuel lines are free of kinks or leaks.
