Help re: Hot head to bulk fuel

[mutti]

Good evening all.

My daughter has bought me a connector so that I can connect my hothead via hose to bulk propane.  I have a 6k bottle sat ready and waiting and my mum (with help from daughter) has has ordered me a flashback arrestor and quick release coupling (birthday on Thurs).  I have jubilee hose clips but I don't have hosing.  1.  What size do I need to order for these to fit ie 6mm or 8mm.  2.  What end fittings if any? screwy nutty bolt fittings etc do I need.  HELPPPPPPPPPPPPPPPPPPP
