What does a performance fuel rail do?
A fuel rail, one of the critical components of the fuel injector, is responsible for stably supplying fuel, such as gasoline, to the injector. Used in advanced direct-injection gasoline engines, a fuel rail helps achieve high levels of fuel efficiency and environmental performance.
Where does the fuel rail go?
The fuel rail is the long, round metal bar that runs along the top of the injectors and is held onto the manifold with a few bolts.
How much pressure should be in a fuel rail?
The components serve distinct functions: the pump pressurizes the fuel from about 3-4 bar (40-60 psi) to between 100-300 bar (1500-4500 psi). The fuel injectors spray the fuel directly into the cylinders.
What is low fuel rail pressure?
Diagnostic Trouble Code (DTC) P0087 stands for “Fuel Rail/System Pressure Too Low.” It may get logged by the PCM when the pressure inside the fuel rail or the fuel system dives below the minimum levels needed to supply the engine with enough fuel to run properly.
Do aftermarket fuel injectors increase HP?
The technical answer is yes; fuel injectors can add 10 extra horsepower at peak. However, for some car owners, that minimal difference does not offset the increased cost and complexity of switching to fuel injectors or upgrading the existing stock fuel injectors.
Do bigger injectors use more fuel?
There can be a larger injector, running less pulse width, that is actually spraying the same amount or even less overall fuel than a stock injector in certain scenarios, such as cruising down the highway.
How do I increase the flow of my fuel injectors?
Increasing fuel rail pressure to get more through your standard injectors.Fit larger injectors - which can be very expensive;Add an ancillary injector - which can cause fuel distribution problems when the manifold is then required to flow an air/fuel mix, not just air;More items...•
What happens if fuel pressure is too high?
If fuel pressure is too high, your vehicle's engine could be over fueled, leading to many of the symptoms listed below. Some of these symptoms include your engine running rough, poor fuel economy and black smoke from the exhaust.
Do I need fuel pressure regulator?
The Fuel Pressure Regulator is a must have item for any EFI system, without it, the fuel rail will not be able to build up enough pressure to support the injectors with the sufficient amount of fuel, the fuel will instead flow straight through and not reach the injectors.
Does a fuel pressure regulator need a return line?
Requires no fuel return line and fittings from the regulator to the fuel tank. This reduces weight, complexity (routing a return line can prove to be difficult), and expense.
