Guest dero Posted August 6, 2003 Share Posted August 6, 2003 well today was first day of attempting to start this newly built engine, there seemed to be only one problem........ NO GAS the the diaphragm on my mechanical fuel pump seems to be working somewhat but im not getting anything at the end of the fuel rail? any suggestions would be appreciated.

z-ya Posted August 14, 2003 Share Posted August 14, 2003 How do you have it plumbed? Do you have a FPR? If your engine specs are as described in your signature, I would ditch the mechanical pump. Install a good quality low pressure pump that will flow enough fuel to meet your horsepower goals. Pete Quote Link to comment Share on other sites More sharing options...
JMortensen Posted August 14, 2003 Share Posted August 14, 2003 Usually if the pump diaphragm goes it sprays oil all over the right side of the motor. I agree though, ditch the mech pump and get an electric and a FPR. I also found that my vapor lock probs totally disappeared when I switched to an electric pump and got rid of the stock rail. I know there's an isolator in between both, but try touching the rail after the car's been running for awhile. HOT!!! Same with the pump. Even more so when the car is sitting in traffic heat soaking.
