Installation Notes and Tips

Confirm the vehicle’s year, make, model, and fuel system configuration before installation. This module uses a quick-connect outlet, female connector, and blade terminals, so connector and line style should be matched before removal of the tank. The package includes a seal and splice kit, but mounting hardware and lock ring are not included.

Because this is an in-tank assembly, clean the tank and inspect the fuel lines, electrical connector, and sender circuit during service. Verify resistance readings and fuel tank pressure sensor operation after installation to confirm proper gauge and pump function.
