My water pump just went out. Where is the best place to pick one up? Also what brand is good? Thanks

Have a Bosch fuel pump----perfect working order--only has about 6 hrs on it----110 LPH----12v--508 464 070-- made in Germany---$40.00 shipped gig out   http://i1125.photobucket.com/albums/l587/dmndstar87/bth_DSC01198_zpsa804be83.jpg?t=1357609709

Has anyone sourced where to find replacement seals for rebuilding shocks/struts? I have both SHP and non-SHP so either will do.   Thanks.
