I have a 1965 W113. My early style elelctric fuel pump froze from disuse. I tore it down and cleaned it up but though it runs, it does not pump. The internal fuel filter is clean and the discharge check valve seems OK. The shear key in the impeller is intact. Any hints? Any alternative to the high dollar option of changing to the later style pump with the requiremnt for mounting and pressure regulator mods?
Thanks
BB
