14 Hose clamps are often ignored. If you can clean up the originals, just reuse and tighten them up. In this instance, we used ABA hose clamps from Sweden because of their tightening capacity. The ABA clamps don't have any slots cut into them for the screw threads, consequently, the hose doesn't get cut as the clamps tighten. Notice that the upper part of the DeWitts tank has the correct radius and depressed area for proper hood clearance.
