Thanks for your answer. The tubing just came off more easily than I'd like is all. I have no idea what the tolerances are for this tubing but when we are dealing with tenths of a milimeter I have to think it will be ok and won't pop off due to pressure in the loop. I have been leak testing/bleeding for about 24 hours and all is well so far. I am having some difficulty getting all the air out but I'm sure that with time it will all work its way out like it always does. Over all I am very happy with the res and I appreciate all the thought you put into the design. It's innovation like this that keeps this hobby interesting and my wallet empty
