2G Gas gauge problems

[TuJay]

I filled my 2G up to almost full, drove about 40 miles and the gas level hardly moved at all. Today I ran to the bank (about 3/4 mile) away and it says I'm just above half a tank?? How can I fix it?

Check sending unit in tank. Just lift up the back seat and you will see the access panels. Could be a bad ground or wire or just bad sending unit.

You might have to open the unit from the top of the tank located under the back seat.The float may be stuck.

I don't recall the numbers, but when full, the sender unit should display a low number for ohms and when empty, it's a high number. Someone correct me if I have that backwards. If you have an awd model, be sure to check both sender units.
