What kind of hose should I use between the A.I.R. pump and the manifold pipe, and where could I find some? The emissions manual states that the hoses are made of a special high temperature material and that no other type hose should be used. I've seen kits of these hoses but they are for 8 cylinder engines, I have an L6 so I'll need to find a source and buy a length of hose. Any help would be appreciated. Thanks, Joe.
