“This overflow bottle functions as expected and is most suitable. As a car restorer I would prefer that it could take the original black plastic Toyota bottle 'top' to make the new arrangement look a factory item. I notice that the outlet tube fitting is a different size to the original making fitting the old outlet tube a little problematic. This doesn't present an issue to me as a car person, but others may not have the resources at hand to effect the installation properly.
Having said all this, the new bottle works well and is clean - much better than the old stained unit it replaced!”
