Sorry, we couldn't find any existing installation instruction that matched.

Pump would only function a few seconds and go back to low pressure

1. Removed pump frame from casting that connects to gas motor.
2. Of the 3 pistons, two had popped the retainer clips off which releases the tension, and any function of the spring. One of the clips was damaged, the other was reusable.
3. Gear oil in the case was cloudy from water intrusion. Replaced the gear oil.
4. Had to purchase a piston to get a keeper/clip. One spring was slightly bent so I replaced it. On a unit more than 15 yrs old, I replaced rubber gasket even though old one was not leaking.
