I've read in the swap guides that Saturn used adjustable fuel pressure regulators in 95-97 S cars (the regulators mount at the fuel rail)

Anyone know how to adjust these regulators?

I need to kill the last bit of richness from my 95 to get it to where it needs to be....

 

there normally straight forward like a bolt that goes one way to make less fuel coming out or opposite way to get more. typically.

 

thanks-- it's actually a security torx screw
