Fueling & Injection - Best proceedure for cleaning out fuel tank?

I'm going to be putting in a new racetronix fuel pump soon and want to drop and clean out the tank before the new pump is installed. Can anyone give me some pointers on the best way to go about cleaning out a fuel tank?

There is a video here on cleaning out fuel tanks, nothing overly special...empty it and clean it out as best as you can
