I have a 03 screw and the gas gauge is acting weird. It started about a month ago. When I start it it automatically shows the gauge ast half a tank, eventually it will adjust itself but when I start it again it goes to half a tank repeating the process. I replaced the fuel pump and sending unit and it's still jacked up. Any suggestions?

 

Mine does that if I park on a steep hill .

 

Mine is every time doesn't matter on the incline. Did you do anything to fix the issue?
