This can be the fuel pressure relief valve purging pressure to the tank.
This can show up if the fuel regulator (Front fitting orifice) has been
changed to a smaller size. The pumps don't make any noise unless they are
injured.

I had the same howl on a fresh HP rebuilt pump from Ingram. It was only at
idle and was more prevalent when engine was warm.
I sent the pump in and he could not reproduce the sound. Perhaps because it
does not get the extra heat the engine provides? Anyway, he said not to
worry the pump is fine,,, so, I was able to set the idle higher than he
suggests without suffering any trailing throttle back firing. This greatly
minimized the occurrence on this application.

I'm detecting a noise coming from my Spica pump. It's kind of a howling
noise only at idle. I can hear it with the engine running and can isolate it
to the rear section of the pump with my stethoscope. Anyone want to guess?
Oil level is not rising. Car is running well.
