Reply to "Electric fuel pump?"

Hey guys!

The safest way to run a fuel pump is mechanically. With the existance of a 120 gph mechanical pump, I don't know why anyone would go through the trouble & noise of an electrical pump. That's last time I'll bring it up, but I do feel strongly about it.

I have found the Holley oil pressure switch they sell for shutting down the elec fuel pump to be a P-I-T-A. Of course, that was almost 20 years ago. It was a source of fuel system gremlins. I hope the Mr Gasket switch is better.

If you are plumbing a fuel pump to draw from the bottom of the fuel tank for the first time, I would run a fuel filter between the tank & pump for the first tank of fuel, then remove that filter and install a new filter on the discharge of the pump, where it belongs. A fuel pump will pass small debris without problem, it's the large stuff that's been sitting in the bottom of the tank for 30 years you want to keep out of the pump; low flying birds, Jimmy Hoffa, dead mackerel, the Loch Ness monster, that sort of stuff.

FI system fuel pumps put out too much pressure for a carbureted system, I've never payed attention to what the maximum inlet pressure of a Holley fuel regulator is, but I'll bet it's not anywhere near the 45+ psi of a FI system fuel pump. The 2 types of systems just don't mix.

Yes Michael, it is wonderful to no longer have the word "OLD" associated with my "karma" level! LOL! Now I'm a sus-tain-ing-pro, just like you!

Mom would be proud!
