Asian Grocery Butane Adapter

[Thomas E Bowdler]

Fellow steamers,
     I was able to get some butane from an asian grocery store near my
son's home in MD.  It is indeed inexpensive but the neck is too short to
reach down to the top of the cab-mounted tanks on most of my locos.  What
are you using for adapters that function like the screw on adapters for
Coleman/Primus gas cans?
Thanks,
Tom
