Air install, just a couple of questions

[newbie_101]

Hey guys,

I've thrown together a crude CAD of my planned air install. Please let me know if I'm on the right track. The box on the frame will contain the compressor and all valves. This way they'll be enclosed and out of the elements. A couple of questions I have are:

1.) It's obvious from the diagram that the plan is to join the airbags. I'd like to keep them separate but can't wrap my head around the use of a check valve. Yes, installing a check valve before each bag will keep them separate and allow for filling from one valve. However, I don't know how to incorporate a check to be used when deflating without using two valves. Also, if using a check valve, that would mean a separate pressure gauge for each bag to get an accurate reading (a gauge would be needed after each check valve.)

2.) I'll be using 3/8" line, with 1/4" to the gauge, sound good?

3.) Any harm in placing the dump valve that far away from the tank? I would run a hose from the dump valve outside of the enclosed box. As long as the hose can handle the max pressure of the tank I should be o.k.?

4.) I can't seem to find a pressure release valve for the tank. I'll be buying most of the material from suicide doors. Any thoughts?

I know I'm probably missing a ton of stuff so your input would be appreciated. FYI, I didn't put the switches in the diagram. I'll be using the upliffters that came with the truck.

Thanks in advance!

You can look here for the relief valve, as well as many other parts. Firestone, and maybe others, offer a single gauge with dual needles to monitor two bags on one gauge.
