Fuel gauge

I've got 98 Formula and the fuel gauge is going all over the place. I could have just filled up all the way and it could read at 3/4 tank. I was wondering if this could be a faulty sensor or something.

i will try some marvel mystery oil and see if helps clean the contacts some. Most of the time the sender gets dirty. you might need to replace it.

Your best attempt at a "cheap fix" is to run a bottle of Chevron Techron Fuel System cleaner through the tank. Follow the instructions and add it to approximately 12 gallons of fuel and then run it until almost empty. Repeat this again for the best result. Sulfer deposits from the gasoline can mess up the sender and this should take care of the problem if that is what is affecting your gauge reading.
