Gas gauge doesn't read full even though it is

[chaase]

I have an 04 GT and when I fill the car up, the gauge doesn't read full. I have heard this is a TSB on this, but can't seem to find the details on it. If it is something I can do on my own or does it need to go in to the dealer for this.

It also goes low pretty early too if that matters. I can pretty much only put 9.5 gallons at a time in the car before the warning light and gauge are going nuts.

Never seen a TSB on this, but there are others - the float in the tank is what is at fault - if you are very ambitious, I guess you can drop the tank and do it yourself.

Mine is doing the same thing. Sometimes it corrects itself on fill-up and sometimes not. But I think that letting the tank run to empty is adding to the problem. That's the only time I noticed something happened.
