I followed the video for installation. Only problem was original installation had the hose routed through a corner cabinet between the dishwasher and sink. It appears they made the connections before the countertop was installed, and the hose clamps on the line running to the air gap were inaccessible. Had to cut through the cabinet side to free up the connections so that the new hose could be connected to the line running to the air gap. What a pain! Changing the hose itself was a piece of cake. Caution: the reason the original hose was leaking was because an appliance repairman had kinked the drain hose when pushing the dishwasher back in place, cracking it. Be very careful to avoid kinking the hose when pushing the dishwasher back in place in the cabinet.
