Installation Notes and Tips

Fits 2004-2007 Cadillac CTS, N/A. Fits 2005-2007 Cadillac STS, N/A. Clean the fuel tank before installing the fuel pump to prevent future seal problems, as noted in the fitment data. Verify connector style, outlet configuration, and system pressure requirements before installation. Delphi FG1940 uses quick-connect outlets and blade terminals, so matching the vehicle’s original fuel system layout is important for proper fitment.
