Re-looking at your photos, hooking up your pipe directly to the manifold barrel IMHO is not a very good way to go. I would almost guarantee that this is the bottleneck area that is killing your draw.
Gerry, Jim has a fair bit of space. And i don't think this is much of a problem.

About as fire resistant as plastic shopping bags. If either of you ever has someone run your rocket continuously to where the mass gets really hot, that stuff will melt onto the pipe in the 300F-350F range, and begin to really smoke and combust in the 400-500F range.
Easier to install, but makes me think of burning plastic army men as a kid, watching flaming drops of plastic fall off and make a flitting sound as the tiny drop of “kiddie napalm” fell from the army man to the ground.
There may not be enough mass of plastic for a real fire there, but certainly a toxic, stinky mess of plastic combustion products.
I would be inclined to keep a close eye on that any time the stove is running, especially while you are troubleshooting and not operating in a static and “fully dried out” state.
