Fuel Pumps - Electric vs. Mechanical

[MrMagoo]

I agree with madmaxx based on my experience after running a holley blue for three years. I have two years on a mechanical pump now and I like it better.
I did this on the advice of joe lapine, who some of you may know as one of the most knowledgeable FE engine builders around. He told me in his gruff authoritative engine builder voice: "I'd never run an electric fuel pump on a street Cobra". That was enough for me, and I've never had to think about my fuel pump since. My electric setup worked although I did have a flukey ground once that caused the fuel pressure to be inconsistent. My reasons for doing the swap were safety, simplicity, and silence. At idle you definitely hear the whine and it's not a happy sound. Simplicity equals reliability.

Anyway, I just hook up the booster when I start with dry float bowls, and I'm good to go. Don at four seconds flat says when you get up in the 550 Hp range, you need a good electric pump just to keep up your fuel pressure, but if you are below that a mechanical works fine.



The original SC/427 cars did have electric pumps.
