[PSUBS-MAILIST] scuba tanks

[hank pronk via Personal_Submersibles]

Hi All,I just bought two new aluminum scuba tanks to replace my steel HP tank on Gamma.  I am curious if I can get a fitting for the tank to eliminate the valves.  I don't need to remove the tanks and would like to just plumb them in.  Also, I assume they are neutrally bouyant when full ?Hank
