fuel guage issue.

I have a 97 4x4 jimmy and the fuel guage is not working. it perks up and returns to zero when ignition is turned on and after that does not work. am i basically stuck with pulling the gas tank to replace the pump/sending unit or am I overlooking something?

Needs a sending unit,tank has to come out and you can get just the sending unit from the dealer.All you need is the vin off the vehicle bringing the insurance slip with you,the last 8 of the vin and the dealer orders parts by the vin.GM has lots of problems with their sending units.If you replace the whole pump,avoid an aftermarket pump and get a Delphi pump.Airtex and Carter are two to stay away from,they are junk and you will replace them a lot.
