Hello Larry
sounds like you have all you need , I have found that with a little persuasion the round banjo fitting on the boiler end of the steam line will usually twist off as its just a compression fit (you can also refit later), then I use medical grade silicone tubing (thick walled) & have never had a blow off with the pressures a Jensen S/V can maintain.
PM me if you need further help.

As the British say I'm about as "thick as two planks" today.  If I remove the banjo fitting I've got the bare metal tubing steamline with the throttle valve included but how and where do I connect it back to the boiler?  I must be missing something but that doesn't surprise me.
