A set of March Performance underdrive pulleys and a Holley Black series electric fuel pump (14 psi, and 140 gph)
Got the oil pressure safety switch and a relay kit to go with it as well.

I have a few questions pertaining to each.

Pulleys: Those of you who switched to the 5070 kit, what size belt did you have to get?? Id like to have it there for when i swap the new ones on.

Elec. Pump: I am going to install the pump on the rear frame, and was going to run the line right into the stock fuel line going to the front of the car. Is this going to slow my gph or psi rating??
Also, how do i go about wiring the pump through the safety switch and relay?? (also to pump fuel when starter is engaged if possible??)
Thats enough for now, but im sure ill think of more.
Thanks

Mine is mounted on the inside of the frame between the tank and the passenger compartment. I mounted the relay in the jack storage bay allowing for a short wiring run from the battery to the relay and on to the pump. I used two triggers for the relay, one from the ignition start postion straight to the relay and the other from the key on position through the oil pressure switch to the relay.

Thanks Dave, im sure i could figure this all out with instruction, butt as usual im anxious!!
Where can i find a hot wire only when the key is in the "ignition start position"??

I spliced into the sol wire to the starter and made my connection on the down side of the oil pressure switch. That makes it where you only have one wire running back to the relay. BTW, I did install a circuit breaker between the battery and the relay.

Thanks again dave, why the need of the circuit breaker?? why not just an inline fuse?

what is the proper way to wire accessories anyway?? i feel like everytime i add something (radio, msd 6al, electric choke on my carb, line lock) that im just borrowing power from another wire? cant be good :rolleyes:

I'm not a real "electricon" :D but the "borrowing power" issue is the reason for the relay (electric operated switch). The fuel pump is fairly high amp so I prefer to come straight off the battery, and also prefer a breaker to a fuse. All the "borrowed" power is doing is activating the relay (to close the circuit from the battery to the pump) so it is a very minimal drain on the trigger circuit.
