should go by the tanks Gage
This will explain it all for you:
Much thanks.... that kinda says it.... my only thing though is that wen I was hand pumping I was pumping the gauge up to 200 bar on the hand pump which got the gauge on the guns gauge to 200 bar ish...now the gauge is small so it is kinda hard to see...
The tank has a 2900 psi reg on it which is 200 bar.Should I assume the gauge on the gun is off?
