OE-Style Replacement Details

This Delphi fuel pump hanger assembly is engineered for gasoline fuel systems and is specified as an in-tank unit with an external strainer.

Installation Notes

Before installing a new fuel pump hanger assembly, clean the fuel tank to reduce the risk of contamination entering the replacement unit. Delphi recommends using fuel tank cleaning kit FC01 for the listed applications. Verify 40-gallon tank configuration and Harness Code # VEH&VEX before installation, and confirm all electrical and quick-connect interfaces match the original setup.
