I have tried three time to stop a very small leak at the fuel valve. It is the pipe thread portion of the fitting going in to the valve. The line then goes to the fuel pump. I am now considering replacing the valve with the Andair to get rid of the fitting. Question I have is will I have to redo the fuel lines in order to replace the valve. I plan on getting the Andair valve through Vans. My craft is a 7A. Thanks
