MAP sensor line

[geartech]

I have been going over my new 1jzgte Supra and I noticed the map sensor line came off of the manifold from a small round check valve looking screw in fitting. and above it is a normal vacuum fitting.
I've been looking everywhere and cant find out what the screw in fitting is and if the map line is supposed to come off of there.
I assume it's correct the car runs fine.

yes, that screwed in fitting is the MAP sensor filter. the line to the MAP comes from that fitting

Thought that's what it was. Saw something saying it's a filter of sorts to keep fuel out of the map line. I remember 80's model gm cars mounted the map sensor lower than the eng and the map line would fill with fuel vapors and then condense back to liquid. I made lots of money diag and fixing those problems. Gotta love GM ( job security)
