For those wanting a 4 tire inflation system, below is how I built mine. All the parts can be had on Amazon. Just cut and paste the exact description in the list into Amazon search and you should come up with the part. The total costs should be about half to a third of what it'll cost for a brand name, already built set online.
Note that the most expensive parts are the Haltec tire chucks. You can use whatever chucks you want, but I highly suggest using these.
A big NOTE about the Haltec chucks, make sure you get the Haltec H-5265. When you pull them off, the chuck will shut off so no air is coming out your air hose as you go around to the other tires pulling the chucks off. Keeps the exact same pressure in all your tires.
Below are materials lists for two different size hoses. Of course smaller hose will be a wee bit cheaper and take up less room when coiled. I calculated the CFM differences between the two diameter hoses, so you choose what you want to use. For me with the smaller hose and 35" tires going from ~10 PSI to 40 PSI is less than 15 minutes for all tires at the same time (dual ARB compressor), which is fine for me. If I use my SCUBA tank inflator, that time would be just a few minutes.
This setup really shines when you're using a OBDII dongle, I have the OBDLink MX+ (Amazon product ASIN B07JFRFJG6). I use my Android phone that reads real time tire pressure and temperature. While inflating or deflating, I can sit in my (nice and warm or cool, depending upon weather) rig and watch as the PSI goes up/down equally on all 4 tires at once. No squatting at each tire 5 plus minutes waiting for it to inflate/deflate. When it gets there, just shut off the compressor and pull the valve chucks.
If anyone wants the Excel file or a PDF of the list, PM me and I'll send it out. Unfortuntely Woody doesn't allow PDFs or other file formats to post (yet?).
Maybe someday, so till then, just a screen shot.
