i need to know which way i turn the screw on my adjustable fuel pressure regulator does torning it in increase or decrease fuel pressure?this thing is a real pain in the butt to adjust you have to take the plenum off to get to the bolt i dont think that is a very good design please let me know so i can finish my car it jumps between 80 and 100 at idle so i know i have to decrease it thanks chuck

 

Turning it in, increases it. If you cut the screw down shorter, you can access it with the plenum on with an 8 mm wrench. (IIRC, its an 8mm). If you are using a gauge, as you should be, you can look at the pressure as you turn it.

 

ok thanks got a guage i was thinking about cutting that screw to i turned it out a little bit today but you can only get it so much with the plenum on and it didnt make a differance i will be pulling it apart again tomorrow and cutting that screw and then turning it out all the way before putting it back together and if i am lucky it will be much easier to do i will let everyone know how i make out i did manage to fix all the other problems i was having qith the car and the thing is like a rocket now compared to before thanks for all the help i got from everyone on here i would be lost without you guys
