theRED5, I thought I saw something from the K-Factory website about all the ports on the fuel tank being adjustable. Her's the blurb from their site:
The fuel tank has a lower CG than the stock one. It makes the handling much easier. Not only this good feature, it has many adjustable functions, including the adjustable tank lid lever, top inlet & inside inlet. All these three parts are adjustable. You can direct them to the angle you need. There is an inside chamber designed to prevent backpressure tube from being blocked.
Hope this helps. I have a tank on order, was $ 25 shipped from Hong Kong.
