Hi my cars fuel gage never goes fully down. Even when I turn the engine off it still shows quarter of a tank. The warning light still comes on when im running low but the gage at that point says half full. Wt should I do and how much is it gonna cost?

Hello Gayle, welcome to the forum.

Try turning the ignition on and off quickly(don't start the enegine)

On for a second
Off for a second
On for a second
Off for a second
etc.

This usually causes the gauges to return to their lowest point.

If that fails you could removed the cluster, unclip the clear front and gentle push the needle back to it lowest position.
