The machine is a gravely ZT-1540 serial  915054.  It is my wife’s race car.  She has seamed to have punched a hole in the left fender/tank  gravely PN 0034850, that can’t be fixed.  I found one at (almost heaven mower junk yard) at 521 north Main Street Bluffton, IN. 1(260)824-5087 or 1(260)827-0933. I live in NC.  He said he has one but no help to go and get it. If anyone lives down the road, and wouldn’t mind sending me a picture of it, I would make it worth your time or if you know where there is one, please call me John 1(910)233-8552  Thanks  everyone for your help
