HI IF THE PROBLEM IS IN THE DASH UNIT WOULD IT BE EASYER TO GET A HOLE NEW DASH MY GAUGE DOES MOVE IF YOU REMOVE THE HS FUSE THEN PUT IT BACK IN THEN IT JUST GOES BACK TO EMPTY AGAIN WOULD IT STILL BE A PROBLEM IN THE DASH

If you can find the wire from the sending unit from the tank yo can unplug it and reading on dash should goto full or empty scale and then ground it to the frame and it should goto either full or empty ....if it doesn`t the problem is in the dash unit
