Me. I have just broken the quick release fitting off the bottom of the tank.
anyone know where I can get one?

Easy, you are not the first one.

Here you can find the entire hose.

Here en my country, you can bring the piece to a workshop and build one replacement out of bronze, I've seen a couple and worked very well.
A good fast solution for 10 to 20 USD.
