The first is to have AN fittings welded to all of the connections and using proper hose ends to connect all of the lines up. The second is to use hose clamps (Earl's makes some that look like their AN hose ends, as seen in the pictures CapZap linked to above). I am probalby going to use the Econ-o-fit fittings (the clamps that look like fittings) first myself, until I can afford the weld fittings and hose ends to connect the lines up that way. HTH.
