I just wanted to say that bettween Bryans advice, the USD repair manual on CD I bought from Bryan and his parts, this website has been a wealth of information. Before logging on here, I would not have considered rebuilding my own double hose regs. Now it's just another diving related thing I do.
I take great pride in diving regs I have rebuilt myself. I showed Nemrod my Hooka portless DA which I dove at Wazee. I think he was suitably impressed as it looked great and obviously dived well. Thanks to what I learned here, that 50 year old reg works as good as it did when it was first manufactured. Thanks Bryan!
