Nope,the vent went out pretty high.I was able to get to it,by reaching up under the gunwale,just to the front of the pillar a little bit.I had to go down,with my hand a bit,then I was able to push it up,and on.
I did cut up my hand a bit on some rough glass,but i was able to slide the hose on to the vent and clamp it.I don't know,maybe I just got lucky.
Here's where my vent is,you can see it,just under the blue horizontal scaffold tube.It still has the masking tape on it,looks like a nub.
