Spectra Fuel Sender

Which pump and how much pressure do you run? This is something I should probably do.

I am running a Delphi pump for my factory application (1997 G1500 Express 350), upgraded the fuel lines from the crappy OEM hard plastic to AN and run the marine regulator at 62 psi.

I finally got around to finishing my fuel pump. I replaced the pump, and the hanger. I ran a 10 gauge wire back to a heavy sealed Hella relay. Out of the relay I got a 12 gauge wire going to a weather pack adapter harness I made, which then steps down to the 14 gauge wire that feeds the pump itself, which the 14 gauge and 12 gauge wires might be 2ft long total...my main goal was to have the main 10 gauge all the way back to the relay. It don't think it would be worth messing with the original harness on the hanger because it was so short, and we don't stock 10 gauge wire terminals at work for weather pack, but I think it will be fine.

So now the old main power line that used to fed the pump triggers the relay, the gauge sending unit wire are straight through, it was fairly easy to make, including the relay, I have maybe $35-$40 in it. I also upgraded some of the ground wires that run to the frame and engine, I think I am going to make a new ground wire coming right of the battery. Right now it still has the original 20 year old cable, which is only 4 gauge that runs to the engine and then a 10 gauge or so that goes to the fender. I want to run a 2 or 4 to the engine, and the frame, and maybe a 6 or 8 to the body. it's probably overkill but I always like heavier cables than needed.

Thanks again for everyone's input!

I had a bunk sending unit as well that was causing all hell. Replaced it with a Dorman and also made dedicated grounds to chassis, and put a Quick Fuel Hotwire kit in it.
