ChrisTH Occasional Poster Location: Thailand Registered: September 2005	Re: fuel pump stops when hot (again) Sun, 09 October 2005 11:21 I did not have my tank leak fixed. Sunday, even here in Thailand. But I did have some time to do some thinking. Am I (or we) doing something wrong? What I mean, do we cause our problems because we want to be "bigger and better"? An EFI pump that is able to deliver excactly the amount of fuel needed for peaks is optimized for the engine. If you replace it with a pump doing twice the flow, what is your gain? I guess.. Nothing. What might in fact happen is that the pump (over capacity) will turn the fuel system into an auxillary engine cooling system. And that is not what the fuel system was ment for. EVOSTi. I dont mean your new lift pump, that will probably ease your problem, but also might not solve it completely. A question to people reading this thread. Would it make sense to turn the EFI pump into a 2-speed pump? By that I mean, add a resistor to lower the voltage while the engine has low fuel consumption, and then with a relay (controlled maybe by the ACIS signal) supply the full voltage when then engine needs a good supply of fuel. I dont know how a normal EFI pump will react/perform on a lower voltage. The idea is not to let a high volume EFI pump use its overcapacity to cool the fuel rail. Simple as that. Any comments?
