Is the pump the old style Holley, or one of the new gear rotor pumps?

Thought we fixed it with a new fuse, believing that condensation from the AC had caused the blow, only to have the same thing on the way home. Once it stopped it would not start without "resting" for 1/2 hour, then it would only run for about five minutes. Changed the in-tank pump and it seems to be OK again. With an external Holley, maybe carry a spare?

It surprises me to hear of an internal pump failure. I thought they're big advantage was running so much cooler immersed in the fuel. I've already made up my mind and planned on going back to the mechanical pump.

Yep, old style. The "funny" thing for me in all this is that I've run this same setup a few times before and never had an issue. Then I get on here and a bunch of folks tell me no way would they run an electric due to the failure rate which shocked me!

Then I go for a simple cruise on one of the last warm days and get stranded by the electric fuel pump.. sheesh!

See what happened??? People got you concerned about the pump and jinxed it!!!! I suppose Holley, like so many other companies, has found a way to cheapen up the build cost on their old style pumps in order to keep the price low.... I'd like to try a belt driven pump (like a Hilborn or K&N), only drawback being you'd have to run an electric pump for start up, then switch over to the belt driven pump....???

Yep.. I'm Jinxed!! Belt driven, sounds interesting but a engineering nightmare.?.?

I had a friend back in New Mexico who ran a supercharged big block bow tie in a vette on alcohol. He ran a belt drive pump. Kept a plastic bottle of fuel with him so he could restart it. I got pretty good at dribbling in fuel into the injector hat until the pressure came up! Certainly not a boulevard cruiser but, it made everyones head spin when we showed up at a local cruise night!

:

I was thinking maybe a pressure switch on the belt driven pump to shut off the electrical pump after the engine is running and generating ___ PSI of fuel pressure???? It would of course require a dual pickup arrangement at the tank... Hadn't really planned out the whole system, but should be able to make it functional and reliable???
