Reply to "Two fuel pump in serie"

Ron, it definitely pumps through the mechanical. In my case I have the Holley mechanical in there too.

The Holley electric pump is one of the quieter units available but it can be annoying to listen too for sure.

I think more times than not, the decision is based on that sound issue alone?

Even so, if you just had the mechanical and you let the system run dry, you just need to turn the engine over more so to get everything primed.

For me, that means maybe the battery is not charged enough to do that more than a couple of tries?

In the end it comes down to personal preferences and sometimes previous experiences whether they be good or bad.

The point about safety on an electric pump without a safety shut off device REALLY comes home to roost if the scenario is an unconscious driver in an upside down car? Holley does have a no oil pressure safety switch to plumb into the engine and wire into the pump.

It's cheap but even so, how much is your life worth? A lot more than the cost of the automatic shut off switch.

It is an excellent idea for anyone running an electric fuel pump. I agree on that 100%. You have to have one.
