[QUOTE="Demon, post: 678147, member: 8347"] Overflow valve. It's the banjo bolt.that holds the return line on the pump. There's a spring and check ball in it. Common for the spring to break or be so weak it doesn't seat the ball anymore. There's 2 styles. Adjustable and non adjustable. Either one can loose the spring.
