After waiting 3 months, I finally got the tank from Kilby. I mounted it and my manifold and got the plumbing between the two finished up. All that's left is to run some hose to the ends of the Jeep and a little wiring.
I removed the shelf where the ABS controller would sit if equipped and mounted the manifold there.
Coalescing filter, 1/2" check valve and 160 psi liquid filled gauge.
I mounted the cutoff switch remotely because of it's size. It also allowed me to get it as high as possible.
I went with the 2.5 gallon version. I still need the drain cock.
