Looking for Valve Kit info on a Black Max Pressure pump 308653009

Have a Black Max pressure washer model#BM80913A     The Pressure pump states it is a 308653009.
No water pressure at all.  Took the brass section off of the bottom of the pump and can see that a couple of the valves are destroyed.
Is there a valve and O-ring kit for this pressure pump?  Or is it just more cost effective to order the pressure pump??
 
Appreciate any advice.
