I did it myself. Do you have experience working on cars? This one can be tough.

here is the diy http://www.a4mods.com/index.php?page.../fuelpump.html

Couple of pointers, when twisting the pump to remove it the hammer method did not work for me. I wrestled with it for a while then used the handles of channel locks placed in the pump to twist it and it worked perfectly. Secondly, when putting the pump back in it can only go one way and it should drop right in.

The fuel pump will do that when the fuel filter starts to get clogged. If you haven't changed the fuel filter yet you might want to do that before replacing the pump.

If the problem does turn out to be your fuel pump, this would be a good time for an upgrade :-)
