Fuel pump question
I need to replace my fuel pump and was thinking of going with an electric pump. Has anyone else done this, is it easy and finially is it worth it? I have a 1978 f150 4x4 reg. cab, 400 auto.

I was told it would be an upgrade by a friend and we did do it to our Mustangs when we were building them years ago. Altough we were making a little more power than this motor, haha. I just figured it was an idea since we replacing the stock pump now anyway.

I have done this. I went back to the block mounted mechanical pump but kept the electric one on and switched "just in case" for a while, then just took it off completely. It was noisy and I wanted to remain "original"

Yep, I used to do it to. Once on a 455 Buick GS and another time on a 400 Trans Am. Both of those were making some power where they needed the higher volume of fuel. You 400 is not going to require any more than the stock mechanical pump will give it. Personally it is a waste of your time and money. The stock pump is going to be much cheaper than an electric UNLESS you are buying a cheap foreign made electric pump.

I just put an electric pump on my old Chevy just because I hate to crank the engine for a long time to get it started after it has sat for a week or two. If I could have thought of some way to prime the system prior to starting it, I would have just kept the mechanical one.

This happens to mine when I don't start it for a couple of weeks.Seems like all the fuel drains back to the tank.When I pull off the fuel line that comes from the tank,it,s dry.The best way I have found is pime the line,make sure you have fuel to the carb.Pour some gas down the carb,after that I starts fairly easy.Doesn't the fuel pump have a check valve in it?

I have a Holley electric pump on my 77 F250, it work great. Starts as fast as a FI system even after sitting for a few weeks, just let pump run 3 - 4 seconds before I crank it. My 83 Mustang with a mechanical pump would be hard to start if it sat for a few weeks (had fuel bowl vents).
