View Full Version : gas gauge question
07-14-2006, 01:12 PM
Well, so I ran out of gas last night...again!! I guess it's time to try and fix the gauge again. I put a new sending unit in last year nd thought that would do it, but it still doesn't work. When I turn on the ignition, the gauge jumps up to full and remains there no matter how much gas is in the tank. Do you think I have a problem with the new sending unit or is it more likely that the gauge itself is the culprit?

Maybe you have the wires reversed on the gauge itself?

The problem is in the wire from the gauge to the tank or the tank itself is not grounded well. Take a piece of wire, hook it to the tank side of the gauge and run it to the sending unit on the tank. I usually run it out the door and under the car to the sender. I think you will find it works then. If the original wire is broken somewhere, the gauge will do exactly what you see now.

Most of the time it's a bad ground. Painted tanks, undercoated tanks, rusty tanks or insulation between the straps and the tank, all can cause a NO GROUND problem. Easy to fix, run a ground wire from one of the sender screws to a clean area on the frame.

A lot of electrical problems on vehicles with age or mileage on them are caused by bad ground connections. That dim tail light or head light is usually a bad or dirty ground connection.

Thanks Mike. I appreciate knowing its probably a ground problem. I've gotten a couple good suggestions on how to fix the problem. I'm eager to get at it!

Hi Gene. I just visited your store's web site. I wish I lived closer to you! Thanks for the good idea on how to correct my gas gauge problem. It sounds like a pretty easy fix. I have a friend with a '57 chevy and he has the same symtoms. I'm going to dazzle him now with my "expertise" on electrical systems! Thanks for making me a genius!
