In 2010 they revised the oil tank again (62954-10), AND the electrical junction block (to better protect it from moisture).
They also moved the ECM from under the seat to behind the rear jug.
A 10 psi pressure relief valve was installed in the top of the tank. 1)
If the vent line / vent tube is pinched or restricted, tank overfilled etc., excessive pressure is created in the oil tank.
The valve opens if the pressure in the tank exceeds 10 psi to prevent damage to the oil tank.
The oil return line was also relocated to right hand side of XL models due to the ECM relocation.
It could also be speculated that the return line was relocated to place it farther away from the tank vent line.
