In this video I build a truly modular, DIY 4 Tire Inflation/Deflation System. This build cost me just under $200 in parts and took only a few hours to build. After testing for leaks in the system and addressing them, I proceed to conduct a deflation test to take all 4 tires from 46 psi down to 20 psi and then aired up from 20 psi back to 46 psi.

Hopefully this video helps you if you want to take a stab at building one like this. Make sure to take your time and always measure twice, cut once.
