Hi just found this, it may be useful, had a quick look and one of them suggests Coleman fuel.
I personally would imagine (unleaded) petrol would be fine though, just don't pressurize it too much first time, so you get the hang of it.
It's worth taking it apart and cleaning the whole thing first!
If it works anything like my MSR it'll be a fantastic "jet powered" bit of kit!
I have the feeling that Globetrotter may have used these or something similar, he likes old fashioned stoves and equipment.
