Great parts. Great price
by Joseph from Tallahassee, Florida on May 04, 2012
Wish it included an assembly diagram. My motor is quite old and I am not sure everything was correctly assembled by previous person who worked on it.

lacking instructions for the extra parts ??
by Daniel from Newmarket, Ontario on April 15, 2012
the quality of the pump and seals looks good but it is aftermarket and comes with 2 different seals then the oem pump and no instructions on where the extra parts go there's a 2 1/2 inch o ring that's new and a lower gasket that's also new and unexplained and the key-way for the impella was not in my kit even thow its shown in the image the extra seal is bottom right and same with the O ring bottom right and the key way in the gasket bottom right not in kit and no instillation instructions
