So, I loaned my Sniper to a buddy. He returned it and told me the gauge wasn't working. When I tried to air it up, it started leaking from the ASA. If I switch the ASA on, the marker airs up, but the gauge jumps to something right off the scale. I've tried adjusting the reg; the needle on the gauge moves, but it's off the scale. Even at minimum, the needle sits around 300 PSI.
Is it the gauge, or do I have to pull the whole damn thing apart and start looking for a blown o-ring?
Any help is greatly appreciated. Thanks.
