SOLVED !
sorry, look for it here (2 generations and 2 transmission types. (4 manifolds) , see right manifold, i think that is more close,see evap VSV.
and 4 more for 89/90 years, (89-95 here in usa and more years, world wide)

the vent filter, is when the ecu, switches the valve, the vacuum ends on that port by allowing outside air to stuck in ,to that port and that air is filtered so that dirt is not sucked into the valve. (purpose)
if only the damage is the filter missing then it sucks in dirt and later can clogs or sticks the valve.
if the cracks are bad enough (damage is random in nature) then it might damage the actual valve below, just look carefully see the extent of damage to top of valve. (the valve can be bench tested with hand vacuum tool and 12vdc battery.
here is my 91, 8v, evap hose.
http://www.fixkick.com/engine/8v-Show-bo...age_6.html
with intake filters on VSV
and the alternator is retracted.
sorry i told you wrong, all i have are m/t photos... but there is a nipple for that valve. to hard plenum vacuum somewhere,
and is not TB.
ever get the engine serial number off the left rear flange?
the letter in the center is year
G16Lnnnnnn L = letter year code, is this a 95 or 89 engine.
im looking at your 3 photos now more carefully.... engine swaps and parts swaps are very common this old.
Your TB is 91 or newer
but why does your intake manifold look alike a 89/90
there are 3 water/air sensors there, the front sensor water for gage. 1 wire,
the rear sensor is air (AIT) 2 wire.
the center ECT sensor is the give away, the center has 2 wires from 1991 and newer and 1 wire, on 89/90 why does yours only have 1 wire (this usa engine?)
see the green plug here (91) that is ECT, it has 2 wires, but yours is WRONG.
see mine.

now we know why hoses dont match up.
the 89./90 engines have no EVAP, VSV, NONE.
the 80/90s hose goes to the top TB air horn (not a vacuum there) nipple that your 91 TB does not HAVE.
so there you go , I bet your engine serial is
G16J or K code is 89/90
seen here.

there are only 3 cures,(1 a half)
1: use a correct intake manifold.
2: use Tee tap , on the other hose that is marked DASH pot nipple, and its fixed for 50cents. this is hard vacuum.
3: leave the hose lay free, and let it smell bad, as it will. (venting to air) illegal in all smog station checks, you fail.
here is 89 wrong way

see wrong manifold on left with 1 wire ECT?

PS
, if not in usa.?
the engine, year codes are MISSING. (can be)
sorry, but our laws cover this rule only.
