The gremlins continue!
After installing the pump/tank I took the Mach for a 15 min ride. Fuel psi was dead on untill I jumped it in 2nd. Then my fuel psi sky rocketed to 15psi and my A/F was pig rich. Got home shut it down, then started motor back up and psi was dead on 7 psi and A/F was back to normal. Has to be the fuel regulator..!! The good news was the Magnafuel pump was hardly warm.
Tore the regulator apart and looks like the diaphram is bad. It may be from the Sunoco race fuel which has alcohol in it. I did order a rebuild kit for the Aeromotive regulator. I have also been reading about other people having problems with these regulators. I'll probably order a Magnafuel regulator. They claim to be gas/alcohol compatible
