Fuel Injection Depot - 5.7/6.1/6.4 2006-2023 Returnless Pulse Width Control Fuel System
Are you looking to support big power with your 5.7, 6.1, or 6.4 car? This is the kit for you.
Our fuel-system kits are 100% plug-and-play, saving hours of installation time and frustration. All wiring is pre-made into a complete plug-and-play harness.
The system is pulse-width-modulation controlled. This allows the fuel pumps to operate at approximately 20–25% duty cycle during idle and cruise instead of running at 100% continuously. The result is reduced fuel heating, longer pump life, and greater power-supporting efficiency.
There is no boost switch to activate the additional pumps. The system is MAP-sensor PWM controlled and includes its own standalone pulse-width controller, fuel-pressure sensor, and MAP sensor.
All Fuel Injection Depot fuel kits are upgradeable. The standard two-pump system supports more than 1,000 whp on E90.
