Re: Electric fuel pump vs original mechanical fuel pump

I only use my electric pump for priming and on the rare occasion (mostly when I lived in Calif) to cure any heat-related vapor lock.

Otherwise, I am always running off the stock mechanical pump. I have the electric pump on an ON-OFF switch location under the dash, that is powered off a switched ignition power source.

So for the electric pump to run, the ignition has to be in the on position, and the under dash switch has to be on.

I have the electric pump and a fuel filter mounted back near the tank. My mechanical pump has no issues pulling fuel through the electric pump when it's off.

But that all depends on the style of electric pump used.
