Sewer Hose recommendation to fit storage tube

I have the same issue with my Dutchstar. I purchased the blue connectors (can't remember the brand name) that just push together. For the one attached to the sewage hose I used the rescue tape which basically bond to itself - no issues with leaks. The part that attaches to the sewer hose easily fits inside the tube and the other end screws into the campground connection (4 different sizes). I've used this for over a year and have not had any issues.
