Review on High-Performance Fuel Pump Module Assembly - TOPSCOPE FP3972M - for Cadillac Escalade & Chevrolet Tahoe 5.7L V8 (1998-2000) by Charles Galan

Revainrating 1 out of 5

PSI too low for spare parts

after installation my truck starts and drives but it has no power you can lower it to the ground and nothing it's a project truck so not a daily driver to a Some other things I randomly checked was that the fuel psi results were 45 psi at idle and dropping under acceleration, the application calls for 52 to 62 psi. Many of these pumps only advertise GPM and do not operate at psi. I suggest buying the advertised PSI product along with the GPM.

Pros
  • Easy to use
Cons
  • disappears
