can fuel presure be ajusted? i imagine not but if so how? has any1 ever changed the presure regulator. is somthing suppose 2 be set right?

 

afpr= adjustable fuel pressuer regulator

some people have modified the stock pressure by using shims/washers to mixed results.

 

Usually though, you only need to adjust it when you've done intensive engine mods, like a camshaft or head porting.

It's not something that can fall out of adjustment. The diapraghm in the fuel pressure regulator can tear, though- but it can be replaced. The FPR is under the plenum (spider-looking thing on top of the motor), it's bolted to the fuel rail, looks like a silver disc with one vacuum line going to it.

Oh yeah the vacuum line can crack, too; that would screw up fuel pressure.

 

good lookin out yall. ill check 2 see if i have bad fuel presure

 

I have an ajustable FPR and have pictures of it too, heavly modified and on my car domain site.
