i assume it came with the ''screw plug'' in it.
are you sure you have an ej25 in the car?
count the ''roundish'' ''cam lobes'' on the front on each side of the engine. 2 each side means DOHC ej25, one each side means SOHC ej22 engine.
my point is this, when an ej22 is swapped in the small vac lines like the one in the picture, are some times re-routed, plugged or left dangling.
but if the engine runs well i would not worry about it. it it runs kind of crappy, vac leak crappy, then i would investigate.
usually those vac lines make their way over towards the passenger strut tower to a couple of ''devices '' mounted there. some years there are 2 lines going over, one with a small inline filter, and some years they used a tee to join the 2 together and onlt one line going to the ''strut stuff''.
