Or do I? I'm trying to determine if I need to run a vent line to my
underbed tank. I went with the
bed fill spout and the illustrations I've seen show the spout attached directly to the tank via a short hose, but there is no provision on the spout itself for the vent as it is on the stock unit. Is there another way to run a vent line or is it really necessary? There is also an additional outlet on the opposite side of the tank that I don't know what its used for. Someone suggested that it was there to relieve pressure buildup, but how do you go about doing that?
