Pressure unloader repair kit instructions?

[KansasPete]

General Pump YU5221 Trapped Pressure Unloader - 2175 PSI, 53 GPM,
I purchased Repair Kit For GPU5221 General Pump Unloader. Where can I find instructions for installing the kit?

I don't think there are instructions. This will show you where the parts go.

$3 worth of O rings will fix the leaking problem if that is what it is doing. I believe the one that is the usually the culprit is the one marked #13 on the .pdf MEP posted. You have to use an allen wrench to get access to it. I keep a rebuilt body in my spare parts box and swap it out when the one on the pump starts leaking.
