PO of my car ('73 w/D-jet) had installed carbs and had the fuel pump under the gas tank. The FP was wired directly to the #8 fuse on the panel, and the ground attached at some point above the fuse panel I believe. Anyway I want to go back to having the FP run through the relay on the board in the engine compartment since I'll be using fuel injection. So I disconnected the wire going to #8 fuse (+ FP wire) and made a connecting wire to the Black/Red wire at the front right hand side of the engine compartment which was originally used for the FP. This didn't work to energize the FP at all, nothing when I turned the key and I'm not sure why. Can anyone tell me what I'm missing? There is a FP relay in the board that I believe is good.
