In another thread it was mentioned that with mechanical pumps it is a fact that when the engine stops so to does the pumping of fuel. With electric pumps you get less cranking at start up (fuel evaporated) but if the engine dies the fuel can still be getting pumped out at a high rate.
I will be running Efi with 2 pumps and cross over valve - when selector switch is clicked over right to left the only fuel gauge will pick up from the other tank.
So how could this setup work if I wanted it to "die" with the engine? Presumably on the oil pressure switch through a relay (to allow for current required for 2 pumps)
BUT hod do I get the thing to start as wothout electricity no fuel pump, end up cranking engine to get oil pressure to activate the fuel pump but by then the battery will be dying! (possibly need a press button t prime the pumps before cranking???)
Can anyone do a wiring diagram that could cope with this? Or am i worrying unnecessicarily for nothing?
thanks
