Escape AWD V6-3.0L VIN 1 (2004)
Fuel Pressure Regulator: Description and Operation
Gasoline Fuel System
The fuel system consists of the following
1. Fuel Rail
2. Fuel Injector
3. Fuel Pump Module (FPM)
4. Fuel Tank
5. Fuel Lines
6. Fuel Filter
The engines are equipped with sequential multiport fuel injection that is supplied by a new returnless fuel delivery system (RFS). The powertrain control
module (PCM) is able to maintain constant fuel pressure by varying fuel pump module (FPM) output. This is accomplished by increasing or decreasing
voltage supplied to the tank mounted FPM. The RFS offers improved economy, lower fuel temperature and decreased fuel vapor in the tank.
