It's more noticeable when inside the car but also you can hear it when the windows rolled down and when you're at a stop or going in reverse but when you start driving no sound. I have a video of it but can't upload it here. It's not the heater core I know that sound very well any ideas? Someone mentioned to check the fuel damper hose.

You sure you don't just have air in your cooling system? Post the video on YouTube and link it.
