I have a leak in the LP hose that feeds my Atomic ST1 regulator. This hose is attached to the second stage via the "comfort swivel." My question is, to replace the leaky LP hose and still be able to use the comfort swivel, do I need to replace the entire hose unit (meaning that the hose and comfort swivel are one unit and cannot be separated) or can I just remove the leaking hose from the swivel and simply replace the hose with another LP (regulator) hose?
