aFe afe42-13011

The aFe DFS780 Diesel Fuel System (full-time operation) for 1999–2003 Ford 7.3L V8 trucks removes water, air and debris from diesel to protect injectors while boosting fuel pressure for steadier supply to the high-pressure pump, improving throttle response and horsepower across the rev range. It features a clear polycarbonate sight glass, contoured CNC manifold, helical spur gears for quieter operation, marine-grade motor, Viton seals and a fuel-pressure gauge port for easy monitoring and service.
