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.

My guess the float is full of fuel and does not follow the fuel level. Our 440 73 Dart currently has a bad sender stuck at bottom so reads empty.

If it works at times it sounds like and intermittent ground. Check all your body grounds. Battery should have a good ground and the engine should have a good ground from the rear of the engine to the fire wall.

Try grounding the gauge first and see if it reads past full. Your sending unit float is probably fine.

I made sure that the fuel tube is grounded to the frame. It usually reads just above empty but sometimes will go up to half. When I fill the tank it will go to full after a few minutes but then back to just above empty. Does that sound like ground problems or sender on the way out? John

BTW last year when ever I drove the car I would put a couple of gallons in to be safe,well when I removed the retainer ring on the unit it was full.Had to quick locate a bucket to catch a gallon or two.

On the back of the gauge pod where the nuts attach the gauges to the circuit board, remove the nuts and clean the corrosion off the circuit flats. I've found these dirty, even loose, causing gauge problems. Clean them all while you're back there. You'll have to remove the cluster to do it correctly. I love the smell of Deer guts in the morning, it smells like... VICTORY!
