I posted  a while back about leaking fuel cells… the ones i had that leaked when you popped the valve in all had a MAY07 date code…  today i had one with a june07 date code that leaked when i popped/pressed in the valve…  after twisting and getting it seated it stopped… but if i hadn’t checked it for leaking it’d have emptied itself… anyone else listen for leaks when use a new fuel cell?  I never did till i ran into a batch that sounded like a tire going flat as soon as you pushed the valve onto the cell….
