Repairing my 2001 Dodge 2500 with FASS fuel pump

I had bad fuel pressure, I thought it was old fuel filters. I had trouble starting my truck and when I hit a bump the fuel pressure would fluctuate. I tried changing the fuel filters but couldn't fill them despite hearing how FASS works. Installed this bypass valve and FASS started on the first try. I showed fuel pressure of 16psi. The truck started with the first hit as it should.

Pros
