Thanks,

Sorry forgot to send you the PM. Will do.
No OE source. The rubber there in the 2 valves are more of a plumbing type one, thick and flat. I have renovated a number of these alcohol bottles and I haven't found one with deteriorated flat rubber. I am not saying that this could not happen. If it did you need to cut one from flat rubber with correct thickness or find a similar one at a plumbing store. The alcohol bottle his is probably the airsupension component everyone could tackle, if you have some of the rubber seal ring you need for the alcohol container (I am using an o-ring here) and i am also using o-rings for the filler cap and connection air filter.

Great you found all parts....and great you have solved the problem. Martin
