I use a JE Adams 7075 or 7085 regulator and loop the bypass to the inlet. They're made for high-pressure, so to get the adjustment you'll have to cut about 1/4" off the spring. I use them because they last much longer than regulators intended for the application, and because it takes some of the stress off the pump. Instead of pushing 125 PSI against a regulator all the time, the pump is only running at your set PSI. It also serves as a safety "pop-off" in you have a check valve in the bay fail - liquid will just bypass the regulator as it's designed to do and flow to the tank with no damage to your equipment or tubing.
I've been using a Spraying Systems type 110 regulator relief valve for the last 15 years on the tire cleaner. I also route the bypass back to the tank. Same Procon pump and relief valve for 15 years of service. Never touch it.
Most Procon have an adjustment screw behind the little acorn nut that you can use to adjust pressure. I have Coleman SS unit and they have regulators on both the air and liquid side. When the liquid side goes bad I just remove them and adjust pressure through the procon. Be careful though, you do not want that screw to come all the way out. Theres a tiny spring behind it that will disappear, then you're screwed.
