You can use the Mallory afpr like you said in our other post. Should be fine. I had to have new fittings for the hoses crimped on. You will have to hook the fuel pump relay up to a 12v source.

Your lights and everything should work fine. If you have duel fans, you will have to hook them up. I am only running one fan and having no problems.

as far as the dist goes. If you get a non computer controlled dist, you can use the Big pink wire and the white wire that goes to the TPI coil. The Pink wire goes to the 12v side of the new dist and the white wire goes to the tach side. Simple enough.

Wait untill you get everthing hooked up before cutting wires. Make sure everything is working and then cut what is not hooked up.

hope this helps. I know I didnt go over everything. Let me know if you need any help.

later

Depends on what year model.

I checked the wiring diagram for my car. I think it had a Green with white stripe, Orange and a brown wire. The other wires were the same color as the other relays. I put 12v to the Green wire with the white stripe. May be different on your car.

Like I said, Depends on the year model.

Check the website again. Right below the 86 vs 87 manifold pickture. Whole paragraph on the fuel pump.

...

However, some of that info is innacurate! I removed the ECM on that car, and returned the fuel pump relay to stock wiring. The oil pressure sensor activates the fuel pump once it sees oil pressure. And with this setup, the pump won't keep going if you crash (potentially very dangerous).
