Is the filter located at the same place for the B6 A4 3.0Q?

<b>Symptoms</b>:
5. disconnecting fuel lines to/from the filter.
<i>WARNING! The fuel system is under pressure. Before opening the system, place a cloth around the connection. Then release pressure by carefully loosening the connection.</i> (when i disconnected the hoses, i didn't notice any high pressure)
to disconnect the plastic clamps on the hoses, just press the color plastic sides with your fingernail (should be a blue, clear, and black). at this point gas will start to drip all over the place. use the rags to soaked it up. use the following sequence as stated in the Bentley manual:
5a. disconnect the clamps on the side facing the rear of the car. you'll see the following:
1 - Fuel return pipe "RL"
2 - Fuel supply pipe from fuel tank "VL"
once both are disconnected, i immediately reconnected them to the new filter in their proper locations.
5b. next disconnect the clamps on the side facing the front of the car
3 - Fuel supply pipe to engine "MOTOR"
4 - Breather pipe "E"
just like the other side, once the hoses are off, reconnect them to the new filter ASAP as gas will be dripping!
6. once all the hoses are reattached to the new filter securely, wipe up any excess gas using a clean rag.

I am having a really hard time taking the hose off I even called it a night because I am already braking the clamps(blue and black). I do see the blue clamp in one of the hoses but I've been trying to loosen it with a flat head but it just wouldn't move. I tried doing this in all the hoses but I just cant figure it out.

I have the same buzzing noise going on that you described coming from my fuel filter. Guess I need to change mine as well. Since I noticed this noise, I noticed another noise that happens from a cold start. When I turn the key to the 'on' position without starting the car, I get a rattle noise that comes from the engine it seems like. But the buzzing noise comes from the fuel filter once I start the car. And the rattle from the engine compartment doesn't seem to happen once the car has been run.. Any thoughts? Thanks

...another thing. The rattle I described when I turn the key only happens for maybe a second or two. Could this be the fuel pump struggling from a clogged filter?
