Thought this might be an option, but it is not. The OEM pump is an interference fit in the saw housing. This pump is not the correct outside dimension and the pump falls easily in and out of the bore where it is supposed to be seated. The pump does not turn freely and has a hitch in it's rotation when turned. Lastly the gear and shaft on the inside of the pump moves slightly up and down in the bore of the pump, whereas the OEM pump was very stable. As much as I hate to say it, pay the money for the OEM pump and get something that fits and works.
The quality was a little anemic on this one. I think it would work if you had nothing else but the one I received didn't hold up during installation. I wound up loosening up the old, original part with WD-40 and reusing that.
