ACCEL 500 Series In-Tank electric high flow fuel pump designed to fit directly into most popular GM EFI applications. Great for EFI conversion and upgrades as the pump design supports up to 900 horsepower on a naturally aspirated application and 700 horsepower on an application with a power adder. This pump is designed for applications requiring more fuel flow while utilizing the factory original equipment lines and mounting brackets. The Thruster 500 can also be used as a universal replacement for applications that require more fuel flow to support additional horsepower while using power adders such as Nitrous, Turbo and Superchargers. Comes complete with installation hardware kit.
