Frequently Asked Questions

Is this mechanical or electric?

Match the pump type to your truck using the listing title and photos before ordering.

Should I change the filter too?

Yes - fit a fresh fuel filter with the pump so sediment does not clog the new parts.

How do I test the fuel pump?

Crack the line at the carburetor into a container and crank the engine; you should see strong, steady delivery. Weak or no flow with a clean filter means the pump is failing.
