Plastic Clamp for Brake Booster vacuum line on all Diesel Vanagon

This is the white plastic clamp that goes around the end of the brake booster hose where it forms a junction.  It could be in the engine bay, or at the brake booster itself.  There is a small screw that doesn't come with it that you will also need to make it work.  The size is 18.5mm and it should work on all Diesel Vanagons.
