    I recently changed my manifold with a used one. I cleaned it out and made sure all plugs and valves were in good shape. I put new o rings on and they are in place correctly. Is it likely for the boss plug to leak or be loose causing overload of fluid around that o ring? Let me know what you guys think

    Do you mean the o-ring boss plug? If the plug with the o-ring under it is leaking then replace the o-ring. Don't use o-rings from a generic kit, they are not the right size. We get our o-rings from the fitting store. Too small o-rings don't seal and too big tend to squeeze out and get damaged causing leaks.

    If your psr relief valve is set too high it still wouldn't be enough to blow that plug seal out. They will handle well over what the pump is capable of producing even without a relief valve.

    the place I got the o rings from usually from western. I'll have to ask. Could it be anything else? The o rings seem to be sitting snug

    Is it leaking at the plugs or where the valve block bolts to the reservoir? If it's the block to red the metal surface may have a mar on it or perhaps paint or dirt.
