Review on Enhanced Fuel Pressure Regulator Spring Kit for 2003-2007 F250, F350, F450, F550 - OE Part # 3C3Z9T517AG Replacement by Matt Pavelko

Bolts that are too small can damage the assembly if not careful

Should have bought a Ford part, it's a Chinese fake. The bolts are several thousand small sizes and if you're not careful they'll rip off your fuel filter assembly. It does not twist to specification. I used Ford screws, which came out and didn't "wiggle" when screwed in. Luckily they got it, I increased the idle pressure from 70psi to 80psi.

Pros
  • Pressure regulator
Cons
  • Almost never
