Hello, I can help with this. Are you looking for a new or used part?
These folks do an excellent job at rebuilding these ABS Pump Modulators but that would leave the vehicle inoperable while you sent it off for repair. http://www.ecutesting.com/wabco_abs_pumps___modules.htmlI had some other sources for used pumps but none of them have any in stock so I believe your best option would be to have yours sent off for repair if you can be without the use of your car for a little while.
