Fuel Line upgrade finnished
well.....got a wild hair and ran 1/2 inch line from tank to carb, and went to a return style bypass system through the regulator.....
Robmc 1/2 pickup to mallory 140 pump to Robmc bypass regulator...using my old 3/8 line as the return (I know, I KNOW....too small)....removed the mech. fuel pump and put a block off plate on. anyway......system works nice...couple things I noticed right off the bat : - I can run with less fuel than before without uncovering the pickup and pulling air(a lot less) - Engine does not lay flat at high RPM....seems smoother? - Engine seems to drop less RPM between shifts - still get some pressure drop at WOT (down to 5) but the engine does not seem to notice - Engine seems to pull very smoothly all the way up the RPM scale I guess the proof is in the pudding.....on to the track

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
