I am running a Holley electric fuel pump supplying a SBC 383. The car is very recently on the road and this problem has occured twice. The pump works fine for 95% of the time. Twice now it has just quit. The fix both times is to let the car sit for a about 10 minutes and the pump starts working.

I have a light in the car that tells me it is getting electricity.
When the pump is working I can hear it. On both occassions I could not hear the pump working.
I have a good ground right to the frame.

I have my pressure regulator set at 7 PSI.

The first time it quit after 5 minutes running
The second time it was working for about 30 minutes and quit.

Any ideas?

Thanks Dave. It is close to the tank so it pushes the fuel forward.

I was thinking the same thing, the puzzling part is it is so intermitent. Today I drove for about 20 minutes. Then it just shut down and I parked it for 10 minutes. It restarted and I drove at least another 20 minutes home with no issue.

I do not have a return line to the tank, I have heard that can cause problems.

The pump is also slightly higher than the tank. I do have a one way value between the tank and the pump so it does not loose prime.

Place the pump lower than the tank and up-size the wiring to the pump and the ground. Most importantly get another pump and the tools to replace this one when it goes and put them in the car.

if you're sure the wiring is good the pump is defect, return it.
