I recently bought a box of goodies at an auction and included in the box was a new AC EP12 (6414671) electric fuel pump. The instruction sheet inside states that the no-flow pressure is 6 psi.

I thought I'd keep this for a back up electric pump but I wonder if the 6 psi is enough for my GMC. Carb - not fuel injection.

Bill,

IIRC, 4-7 psi is standard for GMC fuel pressure.
