I've been leaving my scuba tanks outside, it's 72 in the house and high 90's outside, more pressure, right! So I went out to shoot after work and I noticed when I was filling my gun that the click that you hear from the foster sounded different. I can fill my gun directly off the yoke and don't need a hose so when I bled the yoke to take the gun off something shot out of the bleed hole and splattered on the side of the tank, I looked in the foster on the gun and there appeared to be a bug or what was left after being under 3000 psi. I hope I don't have problems with my gun because of this.
