Elring Curil-T works well, too...and it's easy to get off with acetone.

Seems like even the Pelican rebuilt pumps are a little hit or miss. Worldpac sounds familiar. Of the two I have bought, one was from them and the other was from a different rebuilder. I don't remember which was which. The first one only lasted 30K. The seal started leaking after the second cam belt was put on, and I didn't tension the belt that hard either. The second (current) is ok, but the pulley is very slightly off center to the shaft and the pump is still 10K away from a second cam belt.
