In attempt to understand this problem I went to the trouble of building a bench test rig for the oil pump. I could put what looked like a perfectly good rebuilt pump on the rig, prime it, and it would pump like crazy, Let it set for 30 minutes and it pumped fine. Let it set for 2-3 hours and it would not pump without priming. There is more to this problem than meets the eye and it is not the pickup system.
