I keep saying I'm going to hard plumb mine but it's still hoses every where ,
that's over two years ago , don't forget to dry fit all the plumbing before gluing ,
this would help double check how things fit , looking good
Wow-looks like some gear there. How are you intending to do the plumbing? I admire people who do it as it always worries me
Looking nice, see you have a helper in the third pic . The water leaking would be my worse nightmare. Seen a few in-line co2 diffusers do that locally.
