When modifying or rebuilding and engine, or for a simple FlexFuel conversion, the stock fuel pump is often insufficient and can't let fuel flow through quick enough. The consequences can be disastrous, in the worst case a broken engine (a lean air/fuel mix causing knocking).
Please note that a high flow fuel pump won't increase your vehicle's power. It allows you to replace your existing pump that may be worn or insufficient, and can withstand an increased fuel flow for engine upgrades with high boost pressure, bigger injectors, or other modifications.
