After removing the carpet, you will see a small circular access panel near the rear passenger tire. Remove the three screws, and you will see the access to the top of the fuel tank.
Clip the VW clamps on the hoses (already done in the above pic) and remove the lines. There may be a small amount of fuel in the lines, so have a towel handy.
After these lines are removed, I took a screw driver and hammer to the black "nut" cap. It just screws into the tank (clockwise = tight).
We had a problem removing the electrical plug on the top of the cap. It is not necessary to remove the plug, but will make it easier when disconnected the lines on the bottom of the cap.
In the next two photos, you can see the electrical connectors (the one that is not connected has a black plug) and the fuel and return lines.
The return line (seen the first pic) comes off nicely. The fuel line (don't have a good pics of this) does not. There is another VW clip on it that will have to be removed...
The electrical line (yellow connector) was zip tied to the fuel line. This was nice, since we disconnected both ends and otherwise would have dropped it in the tank.
Once you have the white cap removed, you can get to the fuel pump. You will need to turn it counter-clockwise to "unclick" it from its housing. Do this with grace and equal pressure as you do not want to crack the housing.
We ran into a problem trying to take the flexible fuel line off the white tank cap and the fuel pump. Two more VW clamps on this line that will have to be clipped. The connection on the fuel pump side (plastic) actually snapped.
We carefully removed the line from cap side and replace it with rubber fuel line from a local auto shop (1/4" IIR).
To put the new fuel pump in, just follow the instructions backwards
Be sure to dry all electrical connections and check all hose connectors before trying to start the car.
When you do start the car, make sure to "prime" the line by turning the ignition on and off a few times.
