I wanted to get a true reading of my regulator on my Impact so I looked into a digital guage. I found one for $100 dollars and it included free shipping. It has a 1/4 npt male end I found an adapter 1/8 bss to 1/4 npt for around $10.00 dollars . The Gauge was from www.automationdirect.com the fitting is from www.hydraulicsdirect.com. You will have to take a little off of the bottom of the fitting so it will seal well. I used a lathe but you could use a file just keep it square. I found that my FX guage is off almost 10 bar.
