I could always use some of its own strands, or maybe staple it over in a double hem.
I think I will lay the transformer case sideways and do the accordion style. Less seams means less places for the seams to fail. Just need to find my 16ga wire and hunt around for some scrap rods and roll those into stiffening rings then bale around to secure the narrow portions. I really like the static standpipe you use so what I’ll do is lay the container with the lid facing the tailgate, this will be my clean out. The clean gas exit will go through the bottom and lead up to the cooling rails.
I have a 2"ID 90 degree gentle bend piece of Conduit so I can branch that in on a tangent to the filter.
I might try that either way, wouldn’t be a bad insurance policy on bad seams.
