If you are in the USA you might want to give these guys a call:

They stock all kinds of pumps and are expert at rebuilding them. *You
should also consider that you may have some other issue that is
causing the pump seals to fail prematurely.


Thanks, I sent them an email.
When you say "other issues" do you have something specific in mind?
Bearings are new, engine runs fine.


One possibility is that something is causing the pump to run hotter
than designed. That could be caused by a restricted intake or clogged
heat exchanger for example. If it is belt driven then it could be a
belt tension or pulley alignment issue.
