I bought the Masterflow MF-1050(tsusami) last night, I'm mounting it on the rear RollBar & using my 25' hose with my hand held quick inflater and psi gauge on it.(using no air tank with it)>(Getting rid of that big red tank I have now..................... These Portable Air system can't be run completely blocked, so I need to incorporate some sort of "Adjustable Relief Valve" that release's around 50psi or so. Has any one plumbed in one of these or have the knowledge to point me in the right direction. Maybe remove the PSI Gauge & put some sort of Relief Valve there,, like in my picture.
