Once the can is installed into the pump, it's been punctured? I've been curious about my canister, but I haven't wanted to risk removing it from the compressor in the event that it's a one time shot and will ooze goo everywhere if it's removed.
As for the hose. The hose on mine appears to be mostly clear with no evidence of anything having run through it so I'm pretty sure it's unused.
