2011 V6 Camaro Engine tapping sound?

[Leonhardt]

I am hearing a sound that almost sounds like a tap or an airy click coming from the driver side of the engine. It's difficult to hear at low RPM such as idle (Unless it's cold started until the RPM's die down), but the moment you give the car any gas, you can hear it pretty clearly. The noise is in the video linked.

Anyone have any idea what this may be?

Is this an easy part to replace if you know?

Sounds normal to me, the high pressure fuel pump make some noise. Mounted at the rear of the engine drivers side.

It's sounds like that brand new, they don't go bad as far as I know. Normally they quit working is a sign the engine will not start

It never made a noise like this before, unless it's not the fuel pump that is making it? It's loud enough to hear with the hood closed and while driving past walls or other parked cars, the noise can be heard pretty loudly.

Also extremely noticable when cold started. My concern really is that it's never made this noise before until the last couple of weeks, and the car has 135k miles on it.

Mine gets noisy then quiet back and forth for the past 140k. I just ignore it any more. It is a variable pump so I'm assuming at times depending how its being pulsed it noisy? Just a guess but its something I've noticed for a long time but stopped worrying about it when I realized it comes and goes.
