76 C10 Fuel Reading
My truck is the world biggest optimist. The fuel gage reads full, very full, like the needle is horizontal to the right. Shown as red in the photo. So what do you think, sender unit?

Normal problem you get in each truck, open the lid and clean the complex electrical wiring
 Use W40

Re: 76 C10 Fuel Reading
over full seems to be a broken sender wire,hard to say where
(simple test) ground that wire and it should go to E if everything else is good
