Anyone here running an equalization tube between the intake manifolds on a dual-port VW engines. The guy that built my engine originally had it installed in his Quickie. He says this made his engine run as smooth as a sewing maching and improved his fuel economy. As you can see in the bottom photo, my cowling is quite a bit more snug over the top of the engine that the cowling on the Quickie (top photo). I'm thinking about using flexible tubing for this. Wondering if any of you have something similar.
