Product review (2 stars): What's with the tabs?
The item shipped leaked when installed.  When I compared it to the old one I found two tabs sticking up that prevented the seal from doing its job.  I used needlenose pliers to break off the tabs and after that it seems to be working fine.  Not everyone will be able to figure this out (I'm a mechanic) so not sure that this item is going to work for everyone.  As delivered it did not work.
