Does anyone know what thread size these units come with? And if they’re threaded in and removable?

Trying to change a filter that has zero numbers on it whatsoever. Thought it was a 1-14 thread but the new filter I bought doesn’t fit the threads. I believe it’s a m24-2 thread which doesn’t have many filter options. I think someone swapped the threaded adapter (if it is intact removable).

This the one you have?
Only one labeled Xtreme.
Interesting they have the thread size for every other one listed except that one.
And they offer a filter with no numbers on it.

That's the one. When I called them they told me the same thing it says online. However, I did find that its removable so I can change it out to a size that accommodates more filters from local auto part stores.

Double check this info because I might be mistaken but I think I remember reading that those water separating filters might flow backwards from traditional fuel filters. So just verify whether the fuel flows from outside to in or vice versa and make sure the filter you buy is compatible. I believe the thread is 1-12

*update*

The threads are 12G... Was going to have a buddy machine my a new nipple and have him tap it to 1"-14 or something more common. Hardin-Marin used this thread type so you just about have to use their filter. The problem is the threads going into the housing are 12G also. My buddy's shop doesn't have that tool.

So, I threw up the flag yesterday! I re-rigged the fuel lines and moved the housing, then overnighted a filter from Hardin-Marine. They won this time....LOL
