•  Based on the control signal from the PCM, the fuel pump suctions fuel in the lower cover and pumps it to the high pressure fuel pump. After fuel is sufficiently filtered through the fuel filter (low-pressure) and fuel filter (high-pressure), fuel pressure is adjusted to approx. 430 kPa {4.38 kgf/cm², 62.4 psi} by the pressure regulator.
