You don't actually "need" tubing or anything, but it makes it a lot easier and quicker - I did it by wedging a board to keep the clutch down, opening the valve, letting it bleed until the clutch stuck to the floor, close the valve, pull up the clutch - repeat. The type of valve was irrelevant.
Just wad a thing of paper towels or rags under the block/line and work efficiently, it's a quick swap.
I don't have clear tubing. Is the purpose of the tubing to reduce mess and to be able to visibly see bubbles in the fluid stream? How would you be able to tell if all the air is out if not using tubing? And what kind/size of tubing do I need to buy if using tubing?
