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….. |

My question is can’t I just run the positive wire through the tunnel and ground the fuel pump in front? Doesn't the FI brain control the pump by controlling the GROUND??? In which case your pump would run all the time as soon as you turn on the key ... It's been a while since i dealt with the stock D-Jet, so i could be wrong on that.
