I can't seem to find a 2" hose to a 2 1/2" inlet adapter online. I want to run 4" to the door (filter box) on my longer runs and I don't see them available at multiple suppliers.My 570 has a 2" and a 2 1/2 inlet and my filter box is the same. I am using the quick connects on my hose but don't want to go that route to the filter box. Anyone know where to get them?
