How do you repair a Sleep Comfort or Sleep Number bed that leaks air?

I’ve had two of these beds and both would lose air. It wasn’t the pump. I found the solution to be in repairing and/or replacing the the way the air hoses connect to the pump. The only other solution is replacing the mattresses which is too expensive. If you go to Ebay you can find my solution under Sleep Comfort or Sleep Number beds. I’ve got the solution there with a little yellow book. I’ve found replacement parts that work like a dream.
