    I’ve read the horrid reviews about how they leak and are near impossible to remove after they age but I have also read that it is crucial to lubricate the O-ring (and threads) upon installation to insure that the cap can be removed (without a Sawzall) at your next filter change.

    So my questions is:

    Okay, I’ll lube the threads & O-ring but lube them with what?
    DW-40?
    Motor oil?
    3-In-One?
    Bearing grease?

    I’m afraid to install the new billet cap until I get an answer.

    Thanks!
    I used a little motor oil, just enough to make the o ring wet looking.

    Thanks for the input on this issue.
    I may seem a little paranoid but two things come to mind…

    1.) Oils and petroleum based products are known to swell (and eventually destroy) O-rings. That is why there are plenty of specific non-petrol based O-ring lubricants on the market. (Google it)

    2.) Considering how sensitive the fuel system (and emissions) is on these modern diesels I was being cautious about what I might introduce into the fuel system by lubing the fuel filter O-ring.

    No, I’m not nuts.

    Just a first time diesel owner that’s been slapped around quite a bit by this cold-blooded, somewhat finicky, 2016 Longhorn 3500 of mine.

    Or perhaps it's just'the learning curve' I'm feeling.

    Thanks again!

    Jake, just to let you know Mopar wants you to thoroughly lubricate the o-ring with clean engine oil.

    Re: Fuel filter billet cap.

    I did a thread not to long ago on tips on removing the fuel filter cap.

    Proper tools, give you proper torque to loosen.

    I have had this Billit cap for 25k miles now and no issues.

    I don't understand the issues that people talk about.

    The o-ring that comes with the new filter sits and seats on the factory housing lip and the cap tightens down female to male.

    Maybe I'm not understanding the issues on these O-rings and they are falling off.

    I have only used motor oil on the o-ring. saturated enough that some may run down the threads or even get in the fuel bowl.

    I'm not worried of some small secondary contact to the fuel from engine oil.

    I do not use any type of paste, fluid on threads.

    i want to say 22lbs of gorilla strength.
