The fuel gauge in my GLHS has never read right, tops out just above 1/2 on a full tank.

I've had the stalk out three times, it tests fine outside of the tank, plugged into the harness. Sensor ohms out fine at 100ohms and fuel pump is all the way down and bottomed out in the well in the center of the tank.

Anyone else had this issue? Thoughts?

There any services that rebuild the stalks for a reasonable fee? I have a spare but the return tubing actually has a rust hole in it--

Thanks!
