I recently got a 67 cutlass, I've done some research and find my gauge stays on full. Some say that it's a ground issue at the tank ? I've owned and built a lot of vehicles over the years but the "gas gauge" has always been my nemesis trying to fix. Any info or troubleshooting would be awesome, thanks in advanced. P.s I'm using the app site on my phone and won't let me post pics. Do I have to use the desktop site ?

Sorry, I haven't coded an upload function into the Android APK yet so if you want to upload pictures, its going to have to be on a PC. If it makes you feel any better, to its really easy to do from a computer... just drag and drop.


But yea, definitely check the ground. If there is no rust, dropping a tank is a good weekend job, even for someone like me who isn't much of a mechanic. I don't know about on the 67, but on some later years, you can actually find the sending unit wires behind the license plate. If you take that connect and ground it to your bumper from there and see your gas gauge go to E, that is definitely the issue.

Awesome, I'll definitely give that a try on my next day off. Always being paranoid about fuel isn't fun, my luck it'd be in the middle of town at a traffic light. That's my luck. Thank you again for the advice and I'll be sure to post how it goes.

I've only run out of gas once in a Cutlass (had the same problem) and then just made it a habit to put a gallon or so before drivers. Wasn't too bad since I lived close to a gas station. Good luck
