We usually connect the pneumatic circuit, using the hard fittings between components when possible, and then drill holes in a lexan piece and use small zip-ties.

Do all of your leak checks first, then mount the components.

For example, you can start with a T connector with the electric pressure switch, then use a short threaded coupling, then another T connector with a 120 psi gage, then another short threaded coupling, then another T with the regulator, and so on. Use a connector for the tube fittings at the two ends.

It makes for a combination of components that can be mounted in a solid location.

I will see if I can get a photo tomorrow.
