Hello Oldman Mopar. I did jump the ground to the fuel sending stud. As you described, the dash fuel guage went to full. So, the problem is at the tank. New tank, or different/new sending unit?
Thanks again. Jerry (sgrip65)
I have had brand new sending units fail straight out of the box before. Since then I've started using Kramer sending units and haven't had an issue since. According to them, they test each one before it gets boxed.
I've also used Vans' sending units as well and have had good luck.
