hey all ,I got one for you that hopefully someone can help with.
My complete restoration is almost complete, only needs tires and back bumper. Bronco has been running for a year and have not had a problem with fuel pressure (running at 5psi on gauge at regulator.) The engine is built a bit, edelbrock performer manifold and edelbrock 650 carb, pertronix high performance ignition and an rv cam. Engine was running at about 200 degrees, Thermostat is working great (190) everything was working fine until recently. It now climbs up to 230 and when it gets this hot my fuel pressure drops to zero. Bronco still runs though. I have braided Stainless steel lines from manual fuel pump to regulator and then to carb. if I Shut it off it doesn't want to start, it will with some throttle, just sputters and coughs. I am assuming I am really close to vapor locking. here is the rest of the story. The outside temp here lately has been above 100, got to 109 the other day. so my couple questions are, First can the ambient air temp make that much of a difference, if so what can I do to help cool this (other than not drive it when it is over 90degrees) Oh ya brand new three core aluminum radiator. any ideas? next question is about putting an electric fuel pump on it but I have dual tanks. I have been reading about solutions and one is to install an electric fuel pump back at the tank. So do I just extend the line from my aux tank to that location? Will the electric fuel pump pull fuel from the aux tank if I extend the line? is putting an electric fuel pump a solution to the fuel problem? I know the fuel problem is a result of the heating problem, but honestly I am not sure what I can do about the heating problem. Any advice would be appreciated. Thanks Jerry
