When I pump my gun (Uragan 2), both gauges seem to be in sync.
However, an odd thing happens when I start pumping. First few pumps, the pressure in the hose starts building up. Then, it stops and starts moving incrementally, I assume that's when the tank is starting to get filled. But that happens at a much lower pressure than the tank gauge is indicating. For example, I stop shooting my gun when it drops just below 200 BAR. When I start pumping, first few strokes, the gauge needle advances rapidly. Then, at about 150 BAR, it stops and start moving very slow. Makes me wonder if my tank has 150 or 190 BAR in it.
Any idea what's happening and why?
Also, my pump has fine dust residue the same color as filter material on the bleed valve. Is that an issue?
