This is what I bought from a friend over in the UK.
Ran it like this for a couple months. Balance was WAY off cause the 4oz was mounted to the front.
This is almost how it is set up now. Changed over to an on-off asa that lines up the anti-siphon tube perfect & threw on a couple pieces of stainless hose & quick disconnects for now until I get another piece of stainless tubing & couple more fittings.
