All in all, was pretty weird considering that I had used the marker 10-15 times before this problem came up, and I never dropped it or hit it hard enough to really jar the internals. /shrug

If not it has to be the valve or where the steel braided line screws into the valve. The power tube only has pressure in it while the marker is being fired. Take the marker apart. The valve, power tube, steel braided line and the ASA will all come out in one piece still connected to each other. Once you have these parts seperated from the marker screw a tank into the ASA and pressurize the system. BE SURE TO WEAR YOUR GOGGLES AND HEAVY GLOVES WHILE DOING THIS. Check to see if the leak is coming from the where the steel braided line is attached to the valve.
Then remove the steel braided line from the valve and take the valve out of the power tube. While you have the valve out of the power tube go ahead and inspect the power tube for cracks. Now look into the hole where the steel braided line came out. Check that brass plug for damage. Sometimes the steel braided line will screw in too far and hit that brass plug. Then screw the steel briaded line back into the valve without the power tube. You will be able to see where the leak is coming from.
You may just need to replace an O-ring inside the valve or you might want to replace the whole valve. I would contact BT first as they may replace the valve under warranty. Good luck.
