Ditch the electric fuel pump or keep it?

[Malamute]

My truck has a Holley EFP mounted on the frame rail and while it seems to work just fine, it's very loud and it bugs me. I normally wouldn't care but I have a '66 Mustang that had an electric fuel pump when I bought it and I had quite a bit of trouble with it before we figured out it was mounted too high with respect to the gas tank. I went back to a manual on that car and I've never had another problem.

I'm not looking to spend money in places I don't have to but should I go back to a manual pump? BTW, I searched and didn't find much and that's why I'm asking. Sorry if I cluttered up the board with something that's been discussed before.
