im having the same problem
Have the exact same problem.....can the O-Ring be replaced? On what side it goes?
I had a problem with the quick connect fittings also. I have the BL7000 which I received in early May 2016. The unit worked until I wanted to use it in early June 2017 and when I tried to connect the hoses I felt a lot of resistance and when I finally got the connections made one, of the male fittings on the pump leaked a lot without any pressure applied to the system.
I contacted QuikJack Customer Service and they sent me a one new male/female set of fittings which cured my problem so far. Hopefully that takes care of it for the future also. I may try to find compatible fittings locally so I don't have down time in the future waiting for UPS or USPS to make a delivery.
Thanks for the Customer Service.
Mine was the Male connector at the pump...got the replacement fitting from Quickjack under warranty. great service. So far so good.
