Replace o-ring if there is any evidence of cuts, abrasions, distortion or

wear.

2) Remove valve assembly (retainer, spring, valve, valve seat) from

valve cavity.

3) Remove valve seat o-ring from valve cavity.

4) Inspect manifold for wear or damage.

5) Install new o-ring in valve cavity.

NOTE: Only one valve kit is necessary to repair all the valves

in the pump. The kit includes new o-rings, valve seat, poppet, spring and

retainer. All are pre-assembled.
