Last summer I goofed and melted a hole in my sewer hose with the Aqua Hot exhaust, temp repaired with a coupler and black pipe wrap tape. Ordered new hose from Doug at Drain Master in Holister, Ca. Carried it around until we got back here in Az. because I didn't have two chain wrenches to fit the 3" threaded fitting.
The hardest part was carefully cutting the silicone away from the hose door. You have to remove the steel guard comes out easy, held in place with sheet metal screws top and bottom. Have to remove the outside door which holds one end of the storage tube, then you can pull out the storage tube and pull the hose out. Next took a heat gun and warmed up the 3" threaded connection and used two chain wrenches to un-screw the hose. Bad things could happen it you wrench to hard on the female fitting and elbow, just a word of warning.
Installation of new hose was a reverse process apply a good amount of pipe dope on the threads. Hardest part is the get the sheet metal guard back in place, it hits on the shock mounts, I used my little 1 ton hyd jack and some blocks to get it up in place. I replaced the old screws with a size larger as most of them were stripped out.
Used black silicone to fill in around the outside door, not painted orig color but way down there nobody will notice.
