Installation Notes and Tips

Before installing a new pump assembly, clean the fuel tank to reduce contamination that can shorten pump life. Delphi recommends using fuel tank cleaning kit FC01 for these applications. Verify harness code and vehicle configuration before ordering, especially on 1988-1989 Buick LeSabre, Oldsmobile Delta 88, and Pontiac Bonneville models. Confirm all quick-connect and terminal connections match the original setup before installation.

Delphi draws on more than 100 years of OE experience and supplier knowledge used by major automakers. That OE background is reflected in the design and coverage of this HP10039 fuel pump hanger assembly, which is built as a standard replacement for select GM applications.
