How to adjust/set fuel gauge needle???
 
Finally fixed my tank selector ground and got my fuel gauge to work. Then all of a sudden I ran out of fuel at 3/4 tank. I then realized my gauge still works and the ground is good but my tank is reading 3/4 of tank foward(too much) and before it was actually a 1/4 forward. How do it dial it up correctly?? Lol

You can't calibrate that gauge. Either the sender is mechanically sticking or the ground connection is not healthy (check the wire that goes from the top of the sender to the frame).

I had a issue once too, my gauge wasn't working, when it was filled its was a little pass F, but wouldn't go lower then 3/4, ended up being the gauge
I think I might have a spare one if yours don't work
Is it a single or dual tank?
If its a dual check all the wires and grounds
Check the wires from the passenger side frame
