You might not have heard the term fuel pressure regulator , but as an imperative component of any EFI system , your vehicle will not operate without it.
If the fuel tank pass-through is blocked completely, too much fuel will be forced into the fuel injectors and cause them to fail.
To make sure there is a proper air and fuel mixture , an adequate fuel mixture is necessary for all driving situations, ranging from idling to low revs to higher revs. This is where the fuel pressure regulator steps up and does its job ensuring that the fuel supply meets the demand.
Used to ensure steady fuel supply, a fuel pressure regulator is needed to keep your car going. Even if there are dramatic fuel demand changes, your fuel pressure regulator will make sure the fuel is flowing properly. Optional quick fuel changeover and internal purge capability. Pressure ranges from -6 to 45 psi. I agree to the terms and privacy policy. Fuel Pressure Regulator Ask Price Sometimes, it becomes necessary to conduct engine modifications and fuel adjustments to promote better engine performance ratings.
To prevent overall performance of the car being affected while it is getting used to the new configurations, fuel pressure regulators are used.
A fuel pressure regulator's job is to maintain constant fuel pressure above the intake manifold pressure. Fuel Pressure Regulator Get Quote. Regulator Ask Price.

Fuel Pressure Regulator Ask Price - High pressure fuel enters a chamber that has the regulator inlet and outlet.
A pressure regulator can still be used to provide some trimming of the rail pressure. The pump-external PCV leads to lower pump manufacturing costs but the proximity of the regulator to the injectors can introduce additional disturbances in injector dynamics. This combined flow is discharged from the pump to return to the fuel tank. Rail pressure control with a PCV is inherently fast because of the proximity of the system input PCV and system output rail pressure sensor.
In other words, the system does not include the delay resulting from fuel passing through the high pressure pump as would be the case for some of the pump metering approaches. Abstract : There are several approaches to control the pressure in the common rail. One early approach method was to supply more fuel than is needed to the common rail and use a pressure control valve to spill the excess fuel back to the fuel tank.
