Well i have an air leak on my Pilot Acs and i hear it coming from the barrell and the feeder i changed the cup seal but still listening to air coming out is this supposed to be normal or is there supposed to be no air coming out. If my O-Ring on my tank is damaged can that be the problem well any solution will be great thanks

it soundslike a cupseal to me. After i installed my new valve i had to lap the valve on the surface to the cupseal in order to get mine to stop leaking. I used a 30 micron lapping compaound then a 5 micron compound on a lapping stone at work.
