Well, here's my two cents worth... First, let me say I don't like aftermarket electric fuel pumps, period! I am using one on my roadster only because the Chevy S-10 engine has no place to put a mechanical pump. I am using a Mr. Gasket inline "micro electric" #12S. I don't know what it sounds like yet and I can't speak to its reliability. I picked this one because the guy at my local parts store assures me that it is a common pump available at many stores across the country. My theory is, and always has been, if I break down in Ballzitch, Arkansas on Sunday afternoon, I don't want to be stuck in a motel for days waiting for some high-zoot one-off part to be delivered.

Having said all that, if I have a choice between using a stock type mechanical pump or an electric, I will take the mechanical pump every time. They are generally more reliable and they have the added safety feature that they stop pumping when the engine stops running.

I once encountered a situation where the fuel line was already installed on the right (passenger) side frame rail, but an engine swap put the fuel pump on the left side. Rather than re-plumb the whole thing, I put an extension on the fuel line and ran it across the front crossmember and then back to the fuel pump on the right. I bent the line to fit the contour of the crossmember and anchored it in place beside the brake line that was already there. It was almost invisible when everything else was in place and, as far as I know, it's still there today... Anyway, there's a possibility you may not have considered.
