Mechanic who worked on my van noticed two deteriorated hoses in engine compartment going between crank case breather and in boot of air flow meter. One is kind of horse-shoe shaped, the other is about 4 inches long and a regular round hose. They join in the middle by a metal fitting.
I got onto Bus Depot site and am totally lost as to how to find these parts - they dont seem to fit any category. I need them urgently as my van wont idle properly.

Anybody know what they are called and where I can get them? Thanks.
