QUESTION: We have new oil ,new filter, cone screens clean, charge pump is spinning but no pressure when tested with gauges

ANSWER: If you are getting a zero pressure reading at the primer pump, it is defective. Rebuild it (the cost-effective option) or purchase a new unit. Good luck! MAKE SURE that you have not accidentally turned a stopcock on the hydraulic line to the OFF position!!!!!!!!!!!!!

QUESTION: Is there a pressure relief valve inside are outside the filter housing . If the charge pump spin how can it be defective

if you are NOT showing pressure, either the pump is NOT getting fluid delivered to the inflow side, OR the pump is defective....I believe the pressure relief valve is integrated into the unit, but again, I am not familiar with this particular model....I am giving a diagnosis based on experience with other units....
