Here are a couple of valves.

The regulator one is geared towards gas cylinders available in the UK, you would need to make it to fit whatever canisters you use. The other valve is a demand valve, just like for scuba diving, it allows gas through only when the engine requires it, when the engine stops, it turns the gas flow off.

I have just imported about a dozen of the diaphragms and valves from the US for some jobs I have to finish off, but they are readily available on eblag for less than 10 bucks the pair, if you search about.
