Had the wur off and on 4 times this evening. Moved the post the bimetallic strip sits on .027" inwards no change. Checked for change with 12v on bimetallic strip. Waited 45 seconds no change. Still at 10psi. Tested strip it heats up. Tomorrow will put regulator only with no spring pressure on the car. Need to see 40psi with this test. I wrote down how much I moved it originally.can't find it now. Thought was like .014".
