It hooks two hoses together.  It hooks two more hoses together.  It
physically supports both hoses as they cross the firewall.  I
*believe* nylon hose barbs would fit the bill.

And it makes a restricted bleeder connection with a shutoff valve
from I forget where to I forget which one of the hoses.  Might need
to drill one of the barbs and screw/bolt in a small valve and nipple
for the bleed. If you didn't want to mess with an actual valve,  just
inserting a small nipple and pinching off the little bleed hose ought
to take care of it.  The original had/has a little folded sheet metal
gizmo inside the small hose nipple.  Conceivably that might be a
bubble separator.  But the whole thing only comes into play when
you're bleeding the system.

Now while your H-pipe is still working could be a good time to
examine it and solder up a replacement out of copper.  It's been a
while so the details are hazy, but there's an orifice connecting the
two sides, maybe 3/16" or so.

That's all.  No magic in either one.
