Building a performance engine or doing an EFI swap? You'll need a fuel pump that can keep up. The ACCEL Thruster 500 is a beast. It's an in-tank electric pump designed to flow 500 lbs/hour at 43.5 psi, which is enough to support up to 900 horsepower on a naturally aspirated engine, or about 700 HP with a turbo or supercharger. It's a direct drop-in replacement for many factory GM EFI applications, using the stock lines and brackets, which makes installs way easier. It uses a durable turbine-style pump mechanism that's also good for pulse-modulated systems. Comes with a full installation kit. Whether you're upgrading a muscle car, a truck, or a street machine, this pump delivers the serious fuel volume you need for big power. Just make sure your fuel lines and filter are up to the task!
