I am in the same position as you with no rubber grommet to seal the opening for the rubber vacuum line for the yellow tube. I am just going to use a piece of tin shaped to a 90 bend with sealant between the tin and the box.

Ah hah, just got confirmation from the service manual. When AC is on, there should be no flow from any vents except the AC vents. So that door needs to be adjusted so it's sealed with vacuum on the white tube, as I suspected.

I bench tested my canisters with approx 7 - 10 lbs of vacuum and the door closes completely in both directions. I did have to clean out the yellow side of the canister with a welding tip cleaner as the rubber hose was broken off and some surface rust corrosion clogged the vacuum. At first it would not pull any vacuum as the inlet was clogged. Just make sure your canister is pulling both directions. The biggest air bypass gap with the door on mine is beyond the door hinge mounting pivot point (appox. 1/16" inch) and that is just in the design of the system. I am a little concerned about the surface rust corrosion on the yellow tube side of the cannister as it is inside the box and exposed to more moisture - Pretty rusty but all works well so I will probably just treat the metal and button it up.
I will be lubing all pivoting points with a dry lube (doesnt attract dust or dirt) before a put it back together.
