Leaking HPA tank regulator

[gimp]

My Pure energy 68/4500 tank is leaking from the outlet. I noticed it yesterday, and it wasn't that bad. I could wiggle the pin around and stop the leak. I used the tank today for a little while, and when I took it off the gun it was leaking a lot more than yesterday.

I'm planning to take the regulator apart and clean/inspect the internals. I haven't found any sort of instructions, or parts diagrams anywhere though. I'm a little weary to just start unscrewing things. Does anyone know how to take apart and rebuild a pure energy regulator?

Thanks

I've had 2 PE regs, they both leaked from the pin valve. I now use an on-off asa, it hasn't leaked since then, it doesn't turn the pin when un/screwing the tank. I to am not confortable servicing a reg.
