Re: Custom Intake Carbureted & Nitrous Setup

Still shaking down the Mach. Now I ran into a fuel pump problem causing my fuel psi to drop when the pump heats up. The rpm's start to osilate like it's struggling and now I can never keep 7psi after setting regulator. The pump gets hotter then hell, not good. Engine started running like crap. Checked everything from proper voltage, clogged fuel filter, cleaned/purged the entire fuel system out, tried different gauges and same results. Found that all spark plug center electrodes were all eaten away from this lean condition. I'm very glad I did not try a shot of nitrous on the street.

This just started happening a week ago noticing my A/F at idle was way to lean. I am replacing the Aeromotive pump with a MagnaFuel Quicksilver 275 pump with -8AN external bypass fitting on the "OUT" side of the pump. I will route this to my fuel tank that has an additional -8AN port. I also installed a liquid filled mechanical fuel gauge with a fabricated bracket I made at home. The gauge will be underneath the hood cowl.
