If it suddenly breaks, go back to the last thing that you did before it broke and start looking there

I never noticed a cap on mine (presumably because it was there), but there seems to be a lump in the picture I marked it with a red x.
Is this what you mean? Probably where they pour in the charcoal.
Just seal it, there should be 3 hose connections as in the diagram, the air pipe on mine was just a short loop of rubber hose, possibly to stop water running into the cannister if it went under water (as long as the engine is through the warm-up cycle, or purging the cannister will just suck water up the hose)

My gen 3 canister looks like this:
So there is a cap.
But can be just a piece of rubber hose with a siphon for the function.

It won't draw in air after the engine is fully warm, it should only purge shortly after starting.
You could fit one of those floating ball valves like on a submarine snorkel or the vent to a ship's oil tank but it is overkill really, it just needs to be splash proof, if you must run with the engine under water take the tube up to your snorkel.

You can't fit a non return valve as air must be drawn in to purge the charcoal of petrol fumes, (and air has to get out when the petrol in the tank expands.)Yeah mine did have a cap on it but for some reason now missing, shall I get a bit of hose and a none return valve so it can’t suck water in as I do take it off roading
