So a couple of weeks ago I decided it was time to take care of a few projects on my 74 2.0 D-jet.
A PO moved the 3 port fuel pump up front under the steering rack, but never replaced the plastic fuel lines. The fuel pump works ok, but is noisy and doesn’t hold pressure when I shut the car off. The wiring for it was also cobbled – two wires were run through the tunnel and plugged into the original fuel pump plug, but apparently the positive wire failed so another wire was run from the relay board through the interior and to the pump. It was still grounded through the tunnel wire and original pump harness. I installed Tangerine SS fuel lines and replaced all other rubber lines I hadn’t already replaced and now I am installing a 2 port fuel pump and filter in the same location. The layout proved quite challenging, but I think I have a good solution. My question is can’t I just run the positive wire through the tunnel and ground the fuel pump in front? I did a search and some refer to running “wires” (plural) through the tunnel and some talk about running “a wire”. I just want to make sure I’m not overlooking something….. |

I'm in exactly the same situation, with a complete fuel system refurbish in process. Seems to be a common theme these days. At any rate this is the first time I've tried something like this and I'm using the standard AA fuel pump relocation kit for a stock '73 D-Jet. I have some questions based on replies to this thread:
Why not just run both ground and positive leads from the engine compartment to the steering rack area? The kit I got from AA supplies a combination wire to do this and I'm too much of an electrical novice to know why this isn't recommended here. Why are the copper crush washers for the supply and return that also came with the kit again not recommended? Thanks, John |
