I’m having a gas pipe made up by John sims that will have a tee off with a quick release valve for my bbq. If your interested I’ll let you know the outcome once it’s fitted .
I have an American bbq but it all depends on what connection it has as the newer ones have the quick release. Once I get the pipe back I can show you as it will work off the onboard tank but use the onboard regulator 37dar.
Are you the guy Gavin took a picture of when mark was fitting some cameras???
