Buying this OE Reservoir may cost slightly more, but you will be buying the correct specification part for your machine - as fitted by the factory. That is surely worth it just for the peace of mind knowing the best possible product has been used rather than cheaper after-market items that may, or may not, be O.K!
Add as many items as you wish to your shopping cart and pay just one fixed price shipping cost for a multiple parts purchase. The same specification part used when the machine was new.
