I just got done replacing the fuel filter in my b6. I started the engine up after i replaced the filter and all was good. When i turned the engine on again to drive off the ramps, i heard a sound from the back of the car. Im assuming that it is the fuel pump. My question is is it normal for the fuel pump to make a noise after replacing the fuel filter? I took the car for a small drive to see if that would help (about 3 miles). when i got back i turned off the engine and started it again with no noise coming from the fuel pump. So is everything ok now or should i be worried? Thanks.
