Fuel Starvation on my 69 Z?

[earntaz]

Lawrence -- I had an old 69 Buick Estate Wagon with a big, big, big engine and I went thru the same drill ... fuel pump, fuel filter, etc. etc. Finally blew out the line back to the tank and that would cure the problem for about 1K miles. She was a battle wagon and sold it later to a dude who dropped the tank and found rust and more rust. So yes -- blow out the line back to the tank ... suggest pretty low pressure as to not shred the sock. I would assume you've already pulled a pump pressure test and checked the inline filter. Also, some Holley carbs came with a sinthered metal filter at the inlet(s) -- make sure they are not plugged. TAZ
