The primary fuel pump is located in the left side of the tank. If you fill the tank up and it still does not start then it is the primary tank. Problem is that now you will have to drop the tank with a full tank of gas. The primary pump is used to pump the fuel to the fuel rail, while the secondary pump is used to pump fuel from the right side of the tank to the left side. I usually replace both primary and secondary so I don't have to pull the tank again if the secondary is also bad.
Are you sure you have a fuel pump problem? What are your symptoms?

how can you tell which fuel pump is messed up?
can you use the secondary in place of the primary if it goes out or do you have to replace the primary?
