I need some help with wiring a 914 fuel pump being relocated to the front fuel tank location exactly like the 75/76 914's. The car is a 1971 914/4 being set up for a carbureted 2.4 six cylinder. My question is about where to pick up the power to run the pump correctly.
I would like it to have any relay protections like the original if that is the way it is suppose to be. I think the positive power is to come from the engine compartment relay board from the forward connector pin 13? I plan on running the positive wire from pin 13 under the driver side rocker panel forward to to the fuel tank bay and picking up the ground from the closest grounding point nearest to the tank bay. Any comments or advice would be helpful. Thank you |

If you still have the original wiring the fuel pump connector should be somewhere under the engine shelf on the passenger side.
Why no just extend your wiring from there to the front? You don't even have to cut the harness, you can literally just add a spade connector to your new wires and plug them into the stock connector. http://www.914world.com/specs/SirAndyCarbFuelPumpRelay.php That way you retain the full factory setup with fuse and relay and as a bonus not a single wire needs to be cut.

(IMG:style_emoticons/default/popcorn[1].gif) Yup! I did this on my 73, and got fancy when I rebuilt the wiring harness by extending the fuel pump power lead as part of the bundle, all the way to the front. But you can certainly do in the tunnel (just be careful to protect that wire where it might be loose and/or rub and short out someday. |
