The ID of BH-59/63 and BH-90 aren't the same.
The hose needs to be crushed between the barb and olive. If the barb is too small, fluid might pass between the hose and barb and the olive might not hold the hose securely enough for it not to eventually slip out.
hmm I thought the same but just went on a 5 mile test ride and it seems fine so far, I'll order the right ones and install next week.
