My fuel gauge is pinned on full and will not move off of it. Any Ideas what it may be.. are there any common problems with the sending units.. thank you

 

try a couple of big bottles of fuel system treatment/cleaner..

sometimes varnish can gum up the float and cause the sender to show either no fuel or beyond full..

if that dont work, then you might have a bad sender, but they usualy will show below ZERO fuel when they go bad, not the other way...

 

Try banging on the bottom of the tank with a rubber hammer. If the float on the sending unit is stuck, this just might free it up.
