This water tank, a gift from Guy in return for some exhaust manifold gaskets, had cracks around the sending unit mounting holes. My coach has no sending unit, so I cut out the portion of my old tank and welded it over the old sending unit opening. The weld seeps along the lower left. I could fix it, but once again the redhead said, NO, we will buy a new one. Oh, darn. After seeing the tank Duane Simmons sent me, I\'m glad we went that way.
