Q:

Gas Gauge on 2005 Volvo S60

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I fill my tank and the gas gauge registers half full and remains there. What causes gas gauge not to register contents of gas tank?

It could be your full sending unit in the tank or your gauge. the best way to find out is to scan the vehicle systems. Otherwise it becomes an expensive guessing game.
