This is the EZ-SX version of the pump, please verify whether you have the EZ of the EZ-SX version. AR does identify their pumps on the label of the pump. The pumps both have the same specifications but ultimately the fitment will be off. To determine if you have the EZ or the EZ-SXmodel check the tubes. If the tubes go out the same side as the spark plug, its an EZ. If your inlet and outlet tube come out of the pump opposite the side of the spark plug then you have an EZ-SX pump.
