My 351W's thermostat housing is leaking again. Several years ago, I replaced my custom made steel surge tank that leaked, with the Finishline welded aluminum tank. The Finishline tank included a cheap, chrome thermostat housing that was slightly warped. After filing down the housing, I installed it with included O ring and leak stopped and everything was fine......untill recently when leak started back. After disassembling tank, the housing warpage is worse than before. Even though a new O ring is thicker than the housing groove and would probably eliminate the leak till the O ring flattens, I would prefer to use a heavier duty thermostat housing. I ordered a stainless steel housing from Summit, but returned it because the neck was about 1/2" too long. Neither Summit nor Jeggs offer any other stainless or billet aluminum housings that will fit a 351w. Anyone have any suggestions as to who might have one available?
