Which pre-filter housing for Katadyn 40E

[AmericanVagrant]

I was unable to definitely determine the answer to this with a search. The used 40E I purchased did not include the pre-filter housing. It appears to be a standard Pentek deal. Maybe model # 158116...?

Could someone verify for me? I'm most concerned about getting the input/output thread sizes wrong, fairly certain the rest is standard.

I believe it is the 158116. This one has 1/4" npt ports and the pressure relief valve button with the clear slim body.
