FUEL SYSTEM
F1–11
F1
Operation
• The fuel jet pump (venturi) is installed in the return passage from the pressure regulator, and fuel in the fuel
tank is pumped to the left side from the right side using the vacuum generated in the passage.
• When the return fuel pressure exceeds a specified value, the relief valve is opened. The relief valve delivers the
return fuel directly to the fuel tank. In this way, pressure of the return fuel passing through the fuel jet pump is
kept constantly below the specified value.
