The tubing split that runs into the engine bay

[Turbo Pig]

in the area of the brake booster. I can't seem to find anyone that will has that tubing in stock in the united states. I did leave a message for Aquamist and I am hoping they will send me a new tube. If they can't help me, who in the united states might have the parts and not just the entire kit. I think it's 6mm.
