GMC JIMMY GAS PROBLEM

2000 GMC Jimmy • 113 miles

Fuel gauge will fluxuate back and forth while setting running or going down road no matter how much gas is in the tank, usually 1/2 to full it goes up and back! Never know true level of gas in tank?

Sender is faulty or you have a broken baffle in the tank
