Gas gauge acuracy with the electric Classic gauges?

260 Views 3 Replies 4 Participants Last post by  grumpy
I have the electric Classic gauges, and the fuel gauge that reads right from the Mustang sender. Usually it will read ok, but sometimes it reads totally full when it is not. The other thing is is that when driving around or reving it, the neddle sometimes moves. Also, it seems to read a 1/8 of a tank more than what is really in the tank. When used in the donor, the sender seemed to be alright. How can i fix these three problems?

I have the Classics and except for the needle moving around I'm not sure I can help you. The needle moving is due to the lack of the anti-slosh module. My gage will move during turns, braking, and acceleration as the gas gets sloshed in some direction but while driving on a level road it's OK. Beyond that, it's dead accurate. When it hits E it's empty! Not like a production car where E means you have about 30-40 miles to find a gas station. On mine, E means in about 2 minutes the engine's gonna quit!

The only thing I can think with your erratic reading is a bad connection, either signal or ground that's causing resistance changes.
