Looking for help

70Cuda · 10-22-2007, 05:27 PM

I have just rewirring my 1970 Cuda with an E-Z wiring harness. It went very well, but I stioll do not have a fuel gauge. Someone told me that I need to make sure that the gas tank is grounded. That is great, but how in the world do I do this??? I have looked in my shop manual, but do not get a good picture of what I need to do. Can anyone out there give me the answer.

Thanks

G'Day 70Cuda,

I'm no expert specially not with wiring,but hey i'll give it a shot.

All they mean by grounding the tank is simply a earth wire running from the tank(i think the sender) to a good earth like the rail or somewhere similar.Pretty sure the one on my Val runs back into the boot.Make sure were you ground it is clean of paint and stuff.

Another prob i got with mine was after painting the tank i did'nt put the metal strap that joins the tank pipe to the fuel line, back on

.

This was causing the tank to constanly read full or empty,can't remember.

Like i said i'm no expert,just relate what happens to me,hope it helps

There should be a screw or stud right on the sender flange. That is the actual part you need to ground. I know, you don't want to drop the tank, but.....

I don'r remember if you can reach the sender with the tank "up" but you might be able to clamp a ground wire onto the fuel pickup stub before it enters the jumper hose to the main fuel line.

You should be able (with a friend) reach up there with a clip lead and ground it by hand to see if you are on the right track.

You should be able to check the hot circuit by grounding the lead to the sender and getting a large gauge swing.

Then, of course, there's always the possibility that the sender itself is bad or stuck on empty
