And after disassembling the entire spout, I was able to clean and get the thing working properly. The spout is still a good idea though be certain to store and carry it upright.
Unfortunately, I had two arguments. the twist seal wasn't as operator friendly as advertized and after one trip, the spout began to break at the rim.
Frankly, I was afraid that if the spout was this fragile, I'd hate for the rest of it to crack and pour fuel all over the inside of my kayak and gear. Thus I retired the spout and returned to my older system.
I suppose making a cozy in my dry-hatch to hold the bottle upright and safe would help but frankly, even I am not that anal though I did consider making a protective cap for the spout.
