If you can hear it only inside, but not outside, it only last under 1-3 minutes until engine is slightly warm (considering that starting ambient temp is around freezing) and it goes away with slight increase or RPM ( under 200 RPM increase) then what you hear is power pulses in the fuel line that do sound like a knock; there are some threads here about it…
Some have changed fuel dampener to illuminate this, some had dealer replace the fuel dampener and fuel pump;
The good part it is not the engine or anything serious at all… just can be annoying if it happens often;
