Had a chance today to develop the plenum port a little better. The best mounting for the intake tubing would be to have it connect off a wall and tube. A U-channel flange with a 3" correcting tube (50-50 split) will get cut and welded into the plenums end and allow for quick and easy disconnect.
With that, I received the tubing today. It's a very tough, double ply neoprene, reinforced with a spring steel wire and UL 94V-0 flame retardant. It's not your average flexible tubing. As an added bonus, it has a very smooth interior when pulled taut for flow.
Disregard the placement of the plenum, as it's not secured in position for the shots.
