Hi, I’m new here! I have a 1997 F250 7.3L Diesel powerstroke, it has dual tanks as well. My fuel gauge for one of the tanks isn’t showing up full when I fill it up, so I’m guessing the sending unit is the problem. Does anyone have any other ideas on what it could be or has anyone had to replace their sending unit?

 

Which tank sending unit is not working and what kind of reading are you getting ?

 

It’s the front tank and everytime I fill it up the needle will say it’s half full and then it’ll just go down like normal.
