fuel gauge problem!

[97GoldXLT]

well.. about 4 days ago I put about 20 bucks premium fuel in my truck, which lasts all of a week for my needs.. but for SOME reason, my fuel gauge is showing A LOT more gas then is obviously in there.. like it'll startup showing a full tank and wont go down.. other times it'll startup showing what looks to be the right amount and other times below the right amount..

does ANYONE know what the issue could be!? any ideas help out!!

thanks guys!

Some times mine does that all i can think is i park on a slight hill and that has something to do with it.

The new gas may have "funked up" the resistor on the sending unit. Tray abottle or two of Techron fuel system cleaner. If this doesn't work, you'll probably have to change the sending unit in the tank.

depends on how much of and incline ur on and what way ur going(up hill, down hill). my moms truck has that problem and the grage said it may depend on if moisture is in the tank........something about it sticks to the measure thingy...idk didnt make scence to me but they "supose" to know what they talk about.......any way they said to try some drygas and see if that corrects it
