I recently purchased an RV-6 with about 200 hours with the original vans fuel selector. It seems a little stiff to me and does not have a good click or stop to know you are in the open position on either tank. I have swithed tanks in flight about 8 or 10 times and have not had any problems, but does not give me a warm fuzzy. Is there any maintance that can be done to it. Maybe some bushings or oring to replace. I have the old slyle lever. I was thinking about getting the new style red one, but I doubt that is going to help. Input is appreciated.
