I'd pull it & measure it.





Pressure isn't likely to come back if this were the case


It could if the demand were low enough as with the shorter strokes it could produce the pressure until the demand ( flow) increases. I'd checkk the rod, if in spec, replace the pump twocents beer


Sounds like all the measurements are at idle, parked. Not in use going down the road?
