Gas line for Westy?

[harvey]

Had a look in the wiki and searched a bit but could not find what I'm after... needing the gas line missing in the pic. Can someone help please with thread sizing or know where to buy flex line from ebay, etc? Many thanks.

Found what I was needing at Jacksons of Old Arley - what a great place! I'm sure many of you know it but new to me. Can't recommend it highly enough.
