Im having a different gas gauge issue than the rest of you. Help!

Just bought this 97 GT a few days ago. The gas gauge stays buried a lil past full tank, whether the car is running or not. Any one know anything about this issue? Would really like to kno when I'm running low.

It's got a BBK 70mm throttle n BBK cai, aftermarket fuel injectors(yellow or orange in color)not sure what brand or lb they are, aftermarket headers again not sure what brand, Flowmaster exhaust. Not sure of any other mods that it may have.

Its probably the fuel level sensor that went bad. 96-98 have the fuel level sensor separate from the fuel pump assembly. Its possible if u bought it the previous owner changed the fuel pump and damaged the fuel sensor. Also could be unplugged but id check sensor first

Ok, so here's the update! I unplugged the sending unit from the harness and there was no movement from the gas gauge, so I plugged it back in. I open palm slapped the bottom side of the gas tank pretty firmly just to see if it was just stuck in the full position to see if I could dislodge it, again no change.

So by this time I had put $60 in gas in it, within about a 7 day timespan. $20 three times, roughly 5.5 gallons each time of premium gas. So I figured I might be having the same issue as every one else. Drove it for right at 2 weeks, and then that dreadful moment when you know you've just run out of gas hits. Of course still no change of the gas gauge.

Luckily it putted right into the gas station. Phew, catastrophe averted. So I guess I'll be change that dad blamed sending unit in the next week or so, to keep from picking up any trash off the bottom of the tank.

I'v got a 87 GT and my gas gauge stayed a little over the full mark to. Only difference is when I turned the key on , mine went almost out of sight past full. Drop'ed the tank, removed the Sending Unit, Cleaned around the hole it came out with a wire brush. Installed a new Sending Unit and problem solved.
