Way over priced. $119.00 for $10.00 worth of O rings. Doesn't even have all the O rings to replace everything. For that price it should have all the springs plungers etc.

Got my cat pump back up and running! The pump was dead in the water. When the old seals failed from being run dry oil had leaked into the pump case and no longer produced pressure. Now it works like new! There are some good YouTube videos that cover replacement.
