All, I thought that the LHS connector was a non-return valve - it's actually called a 'fuel reversion valve' in the parts book, whereas the other side is just called a 'union', this led me to think it was a non-return type.
I've bought some quick disconnect connectors which are brass and chrome plated from a guy in the states - they have a 90 deg kick in them but they look great and are leak proof on male and female end. They are not directional.
The thread size is not right but a mate of mine is knocking up an adapter to screw into the tank 1st.
I'll post some pics on completion.
cheers
