I have a 99 suburban and it's the 98 and older body style. The problem i am having is the fuel gauge is fluttering. It moves really fast, so fast it looks like a blur. A small amount, but it is a painfull to watch. I have cleaned the battery cables and every ground on the truck and that don't help. Anyone have a detail video that show how to test the gauge ? I don't want to pull the tank if i don't have to. Thanks !
