I installed the valve from my original power steering pump into the new pump. Engine runs about 30 seconds and return line rubber hose pops off. I tightened the rubber hose really tight! Seems like way too much pressure in return line. I installed the valve with the flat face out and the spring behind it. My original valve was just a little shorter than the one that came with the new pump, but they are both the same diameter. My serpentine belt is turning clockwise, the pump is turning clockwise, steady stream of fluid comes out of the inlet fitting where the valve is located. Does all this sound normal? Both valves are the same on the small end with the screen. I believe the small end is supposed to go back with pressure and close off the small hole in the bottom of the inlet chamber. The difference between the two valves is from the three rings forward. the midsection of the new valve(doesnt touch the sides of the inlet chamber)is longer than the midsection of the original valve making the overall valve length about 3/8" longer. If the front two rings closest to the face of the valve serve only to stabilize the valve in its bore, then they are the same valve. Can fluid pressure get behind the valve via the reservoir and keep it pushed forward allowing unlimited pressure? I can see fluid in the reservoir circulating as the engine is running, never slows down until return line pops off. Return line pops off with engine idling. Please help me!!
