Frankly I think he has a relief valve problem. He already knows ithe pump produces good volume. About an hour to fabricate a pressure test adapter and test the pump in situ. Unlike a visual inspection the result will be definitive.

I'm definitely doing a pressure check before doing anything with the pump.
