I have the same issue with my 79, and I always put the tank in the cockpit and take it home after sailing. I would love to leave it in the dumpster, but like in a previous post the flex vent in mine is also loose.

I remember a post from a couple of years ago where someone had cut a vent in the dumpster and vented it out into the cockpit. I can not find the posting, and I wonder if that might be a viable alternative. The person that posted those pictures put in a cheap vent that is available at West Marine etc., but might be efficient.

Any thoughts?

Was that the post where someone vented the dumpster through the side riser of the cockpit seat so the air would circulate into the footwell sole area between the port and starboard cockpit seats? If you did add a vent there I'd try to find a "boxer" cooling fan from an old PC or electronics device and run it as an exhaust blower. Check but most will run on 12VDC from the battery.

Definitely as a blower - keep it on the upstream side of the system to blow air in instead of sucking air and possibly gas vapor out.

I thought the idea was to suck the vapor out so you would want it on the downstream side. If you blow air in there's a possibility of blowing gas fumes into areas of the boat where you don't want them.

Then again I may be full of hot air too!

pulling air and gas vapor over a sparking commutator/brush of an electric motor isn't always a good idea.

From what I understand they are explosion proof motors.

Check out #2 under the Installation Instructions and the bottom left corner of the 1st page in this link --&gt;&gt; [url="http://www.attwoodmarine.com/userfiles/store/product/files/1238/turbo-in-line-bilge-blowers.pdf"]Bilge Blower Installation[/url]

Explosion proof: That's why I referred to a boxer fan for a PC or other electronic gear - no sparks to generate spurious RF interference. But also to prevent Ka-Boom!
