Thanks for all of the tip's, I will take the mechanical fuel pump off from the motor block and just get a pump cover plate to cover the opening, And I will be bolting the electric fuel pump at the tank or as close as I can get to it, I'm still thinking:h about how the hot wire will feed the pump but maybe from the key switch and a toggle switch or the oil pressure switch. :B

I just left the old mechanical pump in place. I figured since it ain't leaking oil now, it won't leak oil if I don't mess with it :)
Those fuel pumps like to push better than they like to pull, so close to the tank is optimal, however, like I said, mine is mounted up front and doesn't have any problems even on empty-ish tanks.
Wiring - fused hot wire, split in two, one wire goes to switch then to pump, other wire goes thru oil pressure switch then to pump. I added an "aux" fuse block below the original fuse block just for stuff like this. The ground for my pump was the pump case itself, but I ran an extra wire from the pump's mounting bolt up to the engine block anyways. I didn't run my hot wire thru the key...because...well, key switches fail and that's just one more thing to hot-wire in case that does actually happen.
