fuel pump replacement

What is your question?

2day my fuel pump is being changed. I wanted to change it myself cause I thought the fuel pump was outside of the tank. I was told that it was inside the tank. After that I didnt want to even try to change it out myself. I want to know is it true that the fuelpump is really inside the tank or on the outside. My car is a jetta VR6 01. Can anyone let me know?
