AutoZone has a AC Delco pulsator in-stock for 20.99 If I don't have the pulsator and just the rubber tubing like you said, do I need to do anything?

The Bosch fuel pump doesn't use a pulsator, as it's not needed. Read the instructions that can with your Bosch pump.
Bosch style turbine pumps provide a steady stream of fuel as opposed to older georotor or roller-cell type fuel pumps that provide fuel in high speed pulses. Output from a turbine is smooth, consistent and high volume + pressure. The little black high pressure fuel line that came in the Bosch kit replaces the bulbous, brass and plastic press-fit pulsator unit.
