Electric fuel pump failure. Recommendation?

Yeah, v--belt or serpentine belt makes no difference. With a Magnum cam you have to run an electric fuel pump or, use a Hughes cam snout extension.

I run a v-belt on my Magnum and origally ran a Carter electric fuel pump. It didn't last long, so I bought a Holley 1791 electric inline fuel pump and it lasted over 3 years.

I bought and installed a Hughes cam snout extension and put in a mechanical fuel pump. (I used a 1970 timing cover when I built the engine and had it blocked off while running the electric fuel pump so all I to do was remove the block off plate.)

I only have experience with those two but the Holley ran flawlessly.
