After I reassembled the engine on my 91 N/A, I was left with a hose that I can't figure out a location for. It is coming from the charcoal canister, connecting the a metal tube at the rear of the engine bay (the lower one) and then back to a rubber hose on the opposite side. It looks like it used to go in the area near the oil filler, but there is nothing missing that I can see. From manuals, it looks like this end was supposed to go to one of the intake chambers, but again I see nothing. The other end of the charcoal canister is going to the gas tank. Thanks.

theres a nipple on the center housing, for that, it points toward the rear
