Removing vacuum system, plug needed

[TO150]

Hi all, updating avionics and removing the vacuum system from our 1966 Cessna 150F w/O200A engine. The issue I am having is that I cannot locate the correct part to close off the oil separator inlet on the engine accessory case after we remove the tube. I have reached out to Continental and several other resources, but unfortunately, I am hitting a brick wall. I know this is being done and we can't be the only ones, does anyone have any info or guidance would be appreciated!!

Damn it looks like it takes a FAA PMA 1/2" pipe plug?

oes anyone have any info or guidance would be appreciated!!

Post a pic of what was screwed into that fitting. Or if the fitting is no longer needed, remove the fitting and plug that hole which appears an AN plug should work.

It requires an adapter plate. If you don't use it, you will not get oil to the other side of the engine.

Have you seen the exploded parts diagram, maybe it can show us what parts are involved?
Type in O-200-xxxx under Model to see that
