What It Helps Fix

• Noise or drivability issues related to an aging in-tank pump module

Installation Notes and Tips

Before installation, clean the fuel tank thoroughly to reduce the risk of premature seal or pump failure from contamination. Delphi notes that tank contamination is a leading cause of early fuel pump failure, and a fuel tank cleaning kit is recommended for the listed applications. Verify the tank stamping and vehicle configuration before ordering, especially on 1988-1991 Buick Regal, Chevrolet Lumina, Oldsmobile Cutlass Supreme, and Pontiac Grand Prix models.
