Ok,
The sending unit reads at 14 ohms when empty and around 100 at full. Obviously a huge problem. I was able to hook the sender up and watch the gauge. The problem is in the sending unit. I reads at 1/8 of a tank when empty and is incorrect as it goes towards full. Is there anyway to adjust the sending unit or is there a supplier that has a GOOD sending unit. I don't remember who I got this one through.
