I can agree with this. I have 6 DIDs and mixed up the caps only to learn that each cap and top is made to match. Took some back and forth testing to figure out which cap for which DID. Now I only uncap one at a time.
Vapor production can be inhibited but a flooded wick as well. Try some primer puffs first.

Yes. The caps and tank tops are a matched set because the air hole needs to line up. If you have more than one DID of the same size keep track of which cap goes to which because flavor goes down and TH goes up if the air flow isn't right and there's very little chance 2 different ones will be the same.
