Fuel Pressure Question?

Dadada · #1 (**permalink**) 04-21-2012, 02:29 PM

I installed the FRx(fuel rail crossover) from Riffraff on my 2001 F250.The instructions recommends the 62-65 psi spring in the fuel pressure regulator block.The other springs are 58-61 psi and 67-70 psi.I installed the 62-65 psi spring in my truck and it almost seemed like it tamed the truck down.Any ideas or recommendations on springs?My truck has sct w custom tunes,4" mbrp exhaust,Afe intake,Garrett 38GTPR turbo.Do I need to install bigger spring or is this safe for my truck?

Well it should quite it down, but if you feel its weaker try a different spring, that one might be weak

It is a brand new set of springs.I just dont wanna blow anything up,lol.Why do they recommend the middle set of springs?Anybody using this kit?If so,which spring do you use?

just because its known new doesn't make it a known good part

Okay the springs are fine.Physically look like nothing wrong with them and feel fine.No one out there running the Riffraff FRx kit?Need Help?
