Well, sorry to hear it's not working out for you, hopefully you've had that device for a while (the first time I've even seen it offered for sale in months was the thread where you sent me here) and got your money's worth out of it. Regardless, welcome to the Underground - short of trying a new tank to confirm it's a problem with your mod or trying to blow out the connection with compressed air, I'm kind of our of things to try...
