I'm also not seeing any sort of relay to control the compressor. The FIRST legal pressure switch can't handle that many amps. You can use a common automotive relay to control it. wire the pressure sw inline with the relay's coil and you'll be good to go. Look for a universal relay often sold for driving/fog lights, they are typically rated for at least 20a and many are rated for 30a or 40a.

Thanks for the suggestion. I started simple, with a separate manual switch to shut off the pump when at pressure. The next step is definitely to add a relay connected to the switch.
