So I looked up the round valve that comes with doner is called a Clutch delay valve or swirl valve. It's a delay so you don't dump the clutch and stall. Removing it helps the feel of the clutch more direct and rpm's don't bounce on take off. The goblin lines are bent in a way that makes it impossible to use the swirl valve without rebendling the clutch line into the transmission slave cylinder side. So I’ll keep it around but Iam not installing it. In your best interest to delete
