It sounds as if the fuel sending unit is not working and needs to be replaced

Why does my 2002 SC430 gas gauge needle not work when tank is full?

The sending unit in gas tank is broken - hence the wrong readings of how much gas is in the tank. Replace unit.

Says gas is empty but when at the pump its stops filling.some gas exits back from the tank, I figure its my pin any way to find out if im full or not?

What Pin? Your sending unit is most likely worn out,on a 19 year old vehicle. Pull gas tank and replace complete assy,fuel pump and all,while your there.

I have a 1991 ford f150 with a 5.8 engine, most everytime I fill up with gas it spits it back out. I have dual tanks

push the gas nozzle all the way in and maybe the anti theft flaps are stuck easy fix stick a long screwdriver in filler tube to see if they are stuck or if they are jammed in filler tube if screwdriver doesn't detect obstruction try a wire hanger witch is longer and skinnier

Gas Gauge won't move

Replace the fuel sensor / sending unit, it is inside the gas tank, it is a lot of work to drop the gas tank, I have done it on other cars... If you want to do it make sure the tank is almost empty it is very heavy with all that gas inside make sure there is no open flames or cigarretes close
Good Luck

Ford Dual Gas Tank problem, Rear tank Always full.

This is a common problem. On the driver's side frame rail is a large black plastic assembly that the fuel lines connect to. This a fuel switching valve what usually happens is the valve goes bad and the fuel gets pumped from one tank to the other

Fuel Gauge not working

The switch that you use to change tanks is probably faulty - the switch supplies power for the sending unit in the tank, and to the transfer switch for the gas lines - use a meter to check it
