FUEL SYSTEM


  1. CONSTRUCTION


    1. A fuel pump (for low pressure), fuel pump filter and 2 fuel main valve assemblies with integrated fuel suction tube with pump and gauge assembly are used.

    2. A brushless motor is used for the fuel pump (for low pressure). Loss due to brush contact resistance is eliminated, reducing power consumption and achieving improved fuel economy.

    3. The fuel pressure of the low-pressure fuel system is controlled by the fuel pump speed.
