well i just finshed putting in my walbro 255 pump.and when i start it up it has really low pressure lik 30 psi low.and when i try to drive it it seems to choke out really bad.and sounds like a real lowe rev limit.im throwing no codes(chipped pm6) i know i didnt kink a line putting in the tank,but i didnt change the pump sock i washed it out really really good then let it dry for few days and installed it with the walbro.anyone have any clue on what could d cause this?
