Do you have higher fuel pressure, it's very difficult to track down, you get the howl to come in, then hit the relief valve and noise goes away

I can't track it down to. When pump was replaced and it started howling it was always right after engine start then quit when engine warms up. It was about two months not howling at all. Now it start howling again. Sometime very loud sometime just lillbit. Can go quiet after truck fueling.
