My 1983, P303 has Wilcox Crittenden deck fills (assuming original equip). By what I can find on the internet, these were discontinued a long time ago by W-C, I should replace the diesel fill. It has a lot of pitting in the threads and the cap is loose while threading in, it also doesn't seal no matter what size O ring I use unless I over tighten it.
Has anyone had experience in replacing these and know of a substitute from another manufacturer that comes close to the 3 1/2 inch flange and bolt pattern that would work? Also, has anyone had luck in finding replacement caps that would fit?
Any suggestions?
Thanks
Don
