2002 GPGT Fuel Level Fluctuating?

[Brammer]

My '02 GP GT's fuel level is fluctuating. Accelerate or go up a hill, gas level goes up. Brake or go down hill, gas level goes down. While driving normally sometimes it's just wanders on its' own. Fuel level sending unit? Something else?

its likely the sender on the side of the gas pump canister. most of the time its a 20 dollar part.
