Fuel is pulled out of the fuel tank through a low restriction filter and pumped through a fine element filter to protect the injectors from any foreign particles. Fuel is delivered to the engine through special injectors mounted in the fuel rail. The fuel rail is pressurized by the fuel pressure regulator.* Excess fuel/pressure is bypassed through the regulator to the tank. The fuel pressure is set by adjusting the regulator. The proper fuel pressure is extremely important for top performance.
