Yamaha Oil Injection System

Thanks Seakindly for the fine read!!
I have been having a problem with overflowing! and have not figured it out
I have been told by a few that it is the float switch in the main tank?? I have been told by a yamaha guy that it is the control unit??
But this articale says if the Cap on the main tank is not aligned it coud do this also?? I had it off at one point and don't ever remember lineing the Arrows up?? Could it be that simple?? Not for me!! But I am going to check.

Thanks again!!
