Air suction system

Removing the "clean-air system" eliminates the several potential air leak sources at the various hose connections incident to the system.

But be on the lookout for squadrons of black helicopters with bunches of federal marshals rappelling down with their emmission-sniffing commando attack dogs to git'cha! :woohoo:

Good Fortune!

A PO had installed them as deep into the hole as he could get the tap to thread. That was a good method for plugging the holes, so the reed valves and covers were no-longer needed.
The Canadian cover has no reed-valve towers, for some reason. :blink: Canada was/is misguided less than US, it seems.

Is this a problem? The reed on the right is open. I would take it out and flip it but the screws are corroded and one has snappped off. I'll probably just connect them and ditch the whole thing.
