A buddy of mine just installed a TST Powermax3 and 275 injectors in an '01 HO. He installed a Westach fuel pressure gauge and is seeing some variation in pressure. Its 15psi at idle, and 6 to 10 psi driving. Probably depending on how heavy his foot is. But sometimes just driving down the road it will go to zero, and then jump back up. Is this a pump or a guage problem?
