Maybe someone here can help me...I just picked up a PST hp 100 3500psi tank born in 2001 and its 2 inches taller than my al80 (valves not included in the measurement) I was under the impression that the hp 100 should be shorter than my al80. I looked around and found this chart Scuba Cylinder Specification Chart from Huron Scuba, Ann Arbor Michigan According to this chart my tank, if it's a hp 100, should be 2 inches shorter than my 80....that being said the hp120 3500psi from PST is the same measurement of the tank i just bought, two inches taller and the same diameter of the al80. is it anyway to decode the numbers on the tank and figure it out or am I just missing something really obvious? Any help is appreciated!
