So which adapter should I use?
You need the adaptor sold by Jason at the Train Dept (big orange thing above) and then you need a screw-in adaptor.
the long needle adapter with the large thread is for the Butane/Propane mix cans that are about 5" round and 3-6" tall. These have the standard 7/16 gas thread allowing cold weather running with less issues. The orange cap adapter allows you to use the same adapter with the tall paint can sized Butane cans as seen above.
I have made my own adaptor while waiting for delivery of a proper one. (They last a long time - mine has been used for about 0 years now, so definitely buy a good one like the one mentioned above.) Accucraft sells a brass tube they claim will do the job - it fits the 'ronson' filler valve on your tank [you need to acquire a spare one of them, too! BUTANE GAS FILLER VALVE - AP-21761 ]
But I digress. The tube is a GAS ADAPTER OF FUEL EXTENDER - AP-29204 . (I wonder who wrote that description.) One end fits the tube on your butane gas can, the other fits the valve. Unfortunately, no-one has figured out how to hold it still while simultaneously holding the can and the loco. So what I do is make a sleeve that fits the can nozzle and the tube and it holds the tube to the can and releases the gas when I push the whole thing down on the gas valve on the tank.
Call Jason - he'll ship you what you need.
