how are your 6 lines connected? do you have a manifold with 6 outputs? if thats what you have, you need a barbed hose fitting. you'll need to know the diameter of the threaded end on the manifold. home depot sells them in the sink/plumbing area. match the threaded end and pick the one that has the same hose size as your pump. probably 1/2 inch or 1/4 inch. use zip ties to attach the hose to your pump and around the barbed fitting just as an added measure to keep the hose attached.
