thanks, bada... Yes it was a fun if not grueling weekend have jet extensions (screw in type) and notched float. I was previously running a Holley red pump and just replaced with the Holley blue I'm currently having trouble with. I figured the blue should move enough gas if I've been getting by on the red these last few years... I was looking at the black model but went with the blue since it came with the regulator.

I didn't start having trouble until I installed the "better" -6AN plumbing and log. The old system was 3/8 rubber hose and was not technically NHRA legal. At the time I thought the -6 would be 3/8 ID but apparently my understanding of the sizing wasn't quite right

I'm going to try to test the pump sometime this week with a straight hose into a gas can and into another through the regulator to see if it continues to lose pressure... if I can't find anything there, I guess I'll have to drop the tank.
