What is it??

Naturally, I don't have a picture...so, this may be bit more challenging  1970 M20F

When I was in the middle of my oil change fiasco, with the filter off, I noticed a part that was below the filter and and slightly offset to the pilot's side.  It had a small diameter hose (1-2 inch) connected to it that came from the upper plenum on the pilot's side (I.e., the high pressure source of air to this unknown part).  It looked like some kind of 'duct' of an odd shape to cool something, but what?  The mags and the vacuum pump are above it...

I've looked through the parts manual but can't locate anything in that area.  The top of this part is close to round and its top is soldered on, but I couldn't really see the rest of it.  It seems like it is over something that I can't see, either.  It's also a bit 'loose' rather than solidly secured which is what is troubling me.  I'm concerned that it has fallen out of some proper position, (cool the mags??).

Any ideas?

I think some of these planes had a duct to blow air to a shroud around the engine driven fuel pump?

Fuel pump cooler.   some have shrouds some don't

Thanks, guys!  Too myopic to figure out it was the fuel pump!  Makes perfect sense.

Should it be loose?  It kind of rattles around when I grab it and move it.
