fuel gauge never worked right ever since I got the car.I pulled the sender out today to see how much gas was in the tank,its was about 1/4 tank and the gauge read 3/4.would the sender be bad or someone took the gauge pin off and put it on wrong?
its a 90 formula 5.0 5 speed

Re: fuel gauge reads 3/4 at 1/4 full

Bump... I am having a similar problem. My fuel gauge wont read lower than 1/4 tank. If it has a 1/2 tank it will read a 1/2 tank for example, and will decrease as it should but wont go below 1/4. Any suggestions?

Re: fuel gauge reads 3/4 at 1/4 full

From what I can tell this is a fairly expensive problem unless you go junkyard diving to get a used sending unit.

I think I remember a new sending unit being $200 or so?

Either way... my gauge will vary as much as 1/4 of a tank depending on whether I'm braking, accelerating, turning, whatever.

Re: fuel gauge reads 3/4 at 1/4 full

our gas gauges and the instruments that send the readings are serial liars. lol. im fairly sure that the gas gauge is about as reliable as trusting a ford. you never ever trust a ford for transportation. nor should you trust the gas gauge. lol I had the same problem in my old camaro...
