Fire,


A sender which has no ground will read over full. So if yours isn't reading high enough, it probably would NOT be a ground problem. May be a bad sender unit?

might as well check ground anyways. mine read 1/4 over F for a few days. then went back to normal. then eventually it read E for empty but 3/8s for full.

hi man

when i first got my truck i had troubles with the gauges.

take out the gauges. take some sandpaper and stick in the contacts where the gauge posts go. that will get a good contact on the gauges. second remove the plastic gauge holder, pull out the big plug on the circuit board and clean all the contacts with a pencil eraser. dab a little bit of elecrical grease on it. if that dont fix it. you got a bad sender.

I had the same problem with my '67. I found that the float had developed a small crack allowing gas to enter. This made the float arm too heavy to rise to the full mark. I replaced that and it works fine now.

I agree. It sounds like the float.
