Hi gents. The top part of the Pic is my old tank or the one that's on my busa now. The bottom Pic is my new tank. The problem I have is that the fuel gauge unit or fuel meter unit differ from the shape and screws so I can't put my old tank's unit over to my new clean tank. I also have no idea where to buy such a unit I only end up getting the ones where the fuel pump is included with the float unit but my bike has an outside fuel tank separately.
