Regarding retract plumbing, I have removed the hoses from the cylinder barbs on several occasions. You don't PULL them off, you PUSH them off from the base of the barb using any flat thin blade. I've even done it with fingernails (mine are quite tough!) Just be careful to avoid scratching the barb as this can lead to air leaks.
