I made one for the creed/mag from a brass 90 degree elbow drilled through and tapped 1/8" bsp to accept 2 macro fittings. Some stuff isn't available off the shelf and you have to get creative
I've just remembered that I've re-routed the hose since the last picture was taken. The T-junction's now fitted to the inline regulator, losing the loop of hose to the rear for a neater arrangement. I'll try to sort an updated photo later
