I'm getting the little things fixed before spring, my gas gauge in the 71 RR doen't work most of the time. I have a new sender and I do have the ground clip on the line. The wire is in good shape, I do know that much. I have held the ground clip tight in the gas line so I'm PRETTY sure it's not that. Is there a way to check the gauge? The ground on the back of the gauge has been check and is definitely good.
