My google fu is weak today. For the Velocity exhaust on the R, what lines do I need to get?

3/16” vacuum hose.

As always, thank you.

That is the perfect size for the VAP valves but .75 mm too large for the plastic tubes coming off the car's vacuum. Using two hose clamps at that end of the vacuum lines, however, will give you a leak-free connection.

Great. I want to get all things ready for the VAP exhaust I bought form a member here. It should be at my door in a week
