I just put my car back together and I installed a Holley Adjustable fuel pressure regulator. The one with the big *** on top.. Now that everything is back together he plenum is sitting on the *** and I can't turn it.. I thought these were supposed to have enough clearence.. Car cranks and then shuts off 2 seconds later so I figure it's not adjusted right... Did I not turn the *** down enough times before intalling the plenum or what.. Please help...

 

very possible you don't have enough fuel pressure. maybe under 20 psi when they injectors quit working. on mine it clears. on the guy i bought it from, we had to clearance his plenum to get it to fit.

 

Its pretty common to have to notch the plenum a bit to give the adjustment screw clearance. I had to with my AFPR. Mine is not Holley though.

 

Thanks everyone I went ahead and took off the plenum and notched it, works fine...
