Im sure this thread has been around but i am currently replacing rockers and cab corners and removing the box to do so, so i figured id fix my fuel gauge problem as well. i have an 02 lb7 and my fuel gauge usually says full but then it moves to where ever it pleases. So im just wondering what i can do to fix this. ive looked into getting just the sensor but you cant do that for the diesels apparently without buying the whole fuel pump and everything which i do not need so anyone have this problem and have a solution to fix it???
