I purchased a 74 Bronco with EFI where the previous owner installed EFI. He installed what looks like 6 way solenoid valve mounted on the frame and he bypassed the 3 way selector valve for the main and aux, tank. When you stomp down on the gas petal, it's acting like the engine is starving for fuel and does not have the Power I think it should have.. Does anybody know if f I can rerouted the fuel lines to go back through the 3 way tank selector valve with the new EFI system.? Can I install check valves in the main and aux. tank lines to insure there is no back pressure to the tanks? I do know there is supposed to be a fill line and And a vent line for both tanks or is it a recirc line? Previous owner said sometimes the aux tank or main rank (depends on what tank was fuller..would pressurize and spit fuel out of the fill cap.... I really don't understand that statement on why it's could do that. And Lastly could I have a bad fuel Module? If so how can I check it to see if it's bad? There is a plug in on top of it,, possibly for a diagnostic tool. Thanks I'd appreciate any help and if anybody could email me a fuel line diagram using both tanks with the EFI system that would be great. Again that's for any input I can send photos if it would help.
