Those are the idle boost valves for power steering and A/C.  Diagram
on 24.24a and b.

Notice that there are two calibrated orifices in the system, both
associated with the gasoline vapor recovery system.  The large one is
the size of a 1.4 mm or a #54 drill; the small one is less than half
the size of a #80 drill and I'd have to think hard how to make
one.  Find/make a pin to size and punch through heavy aluminum foil
into soft wood, maybe, then glue it across the end of a coupler.

Yrs,
