does the stock fuel pressure regulator have a srew on the top of it, or have I had an adjustable one on there from the old owner and not known it?? it doesn't have any names or anything engraved in it that I can see, should I just get a gage and see if I can adjust it??

 

FstBrd,

If there is a screw in the top of the spring can on the FPR, there is a good chance (virtually 100%) that it is adjustable.

 

awesome, well I got a fuel pressure guage so now I am gunna have to play around with it and hope it works. . . this is awesome if I just saved myself $80.
