Anyone know of a spin on fuel/water seperator filter for the 6.9 that does not require replacing the filter head to the one used for the 7.3? I am aware raycore has a system but was hoping to make it simple by screwing one to the original filter head, thanks Royboy

 

are you deleating the factory one on the firewall? if so good. but i just replace the firewall one with a water seperator from napa. whole kit can be had for 50 bucks or so.
