I actually have two problems. one is the fuel gauge. when i fill the truck up it reads full then after driving for a while it reads empty even though the tank is not empty. there is no in between as the needle goes straight from full to empty. it does this with both tanks. also i noticed fuel leaking down the front of the front tank so i switched to the rear tank. the fuel still is leaking down the front of the front tank. I ran the front tank empty before switching so i have no idea where the leak is originating. does anyone have any ideas?
