Villager V6-181 3.0L SOHC VIN 1 EFI (1997)
Fuel Pressure Regulator: Description and Operation
PURPOSE
The fuel pressure regulator maintains the fuel pressure at 290 kPa (42 psi).
OPERATION
Since the injected fuel amount depends on injection pulse duration, it is necessary to maintain the pressure at the above value. The fuel pressure
decreases as the vacuum increases. At idle when vacuum is applied, the fuel pressure is 235 kPa (34 psi). When no vacuum is applied, the fuel
pressure is 294 kPa (43 psi).
LOCATION
Mounted to the return side of the fuel rail on the LH side of the engine.
