Help , please...
Anyone have advise on how to wire-in rotary fuel pump? I am doing an FI to Carb conversion, and will be switching-out stock Fuel pump. With the harness/ecu unplugged, how do you get 12v to the pump without rewire? The fuel pump relay will not be energized. I had relocted stock pump under gas tank, should I place new one there, or in engine conpartment? Any help/input appreciated as I am beginning job !!

The electric pump will need to be as close to the tank as possible and below the tank if you can. That pump is a "pusher" and works best in that location.
Trace the original wiring to the 12 volt key-on feed and wire it in there. Best and safest is to stick as close to stock as possible. Luck! TC |

It's a Good Thing to use a relay to run the pump. The stock fuel pump relay can be used, if you ground one of the pins in the four-pin connector on the relay board. This assumes you have run the original fuel pump wire up to the front compartment (or have a 75-76, which has the wire going up front).
There have been posts about this, one in the past few days. A search will turn up some photos and at least one or two threads on the subject. --DD |

Not another one! Group: Benefactors Posts: 4,526 Joined: 1-March 04 From: San Mateo, CA Member No.: 1,743  |
Except, Trekkor, that place on the relay board doesn't go through the fuel pump relay. I *may* go through the main relay. Two of the pins on that connector should be bridged together for the fuel pump relay to work as stock. Pins I and III, if connected together will turn on the fuel pump with the key, but through the fuel pump relay, and using the fuel pump fuse (the 8 amp one).
