What are you looking to achieve a cleaner setup, faster ? you got some nice braided lines there maybe buy 8 new valves set them up on a street T (innovativeairsuspension.com has really good ones) with a 1/8" port for your guage lines and mount on setup at each port on the side of the tank with two ports, so if you have two tanks next to each other you have 4 ports on that side and four valve assemblys then use the other side of the tanks and run a compressor to each of those ports.
Heres my old setup sorta like this but it would be on two tanks instead of one, same number of ports though. but only if you want FBSS.
just one way to do it, there are a million ways to setup air ride, depends on if you want to keep everything you have or change some things around, either way I would keep all those braided lines. peace
