Something to watch out for, I did a cross reference for a JX85100-c oil filter to a Baldwin number it crossed to a B7451. It has a 19psi bypass valve. I installed it on my Tytan 403 crawler. I operated it for about 3/4 hr. and loss all the oil pressure. My son is a mechanic and did a lot of checks finally reinstalling the old filter before getting my oil pressure back. Does anyone know if the Baldwin cross reference number for the JX85100-c is wrong or what the problem could be. Where can I buy the original JX85100-C oil filters?
