    I have the D-300 installed in my MJ and I need to get the vent fitting. The hole is there but no fitting at all.

    Does anyone know what size fitting I need to put in there so I can run a vent line?

    Thanks!

    The original was a press in unit with barbs to keep it from coming out. As you found they work loose and fall out. I tap all the ones I rebuild with an 1/8" npt tap and put in a threaded barb fitting or a thread in diff vent depending on what the customer wants.... The hole is already the right diameter so no drilling needed.
