•  Mainly consists of a fuel filter (high-pressure), pressure regulator, fuel pump, fuel reserve cup, and fuel filter (low-pressure).

•  A pressure regulator is built-in due to the adoption of a returnless fuel system.

•  A hard-plastic fuel pump unit with an integrated fuel filter (high-pressure) and fuel pump has been adopted to simplify the fuel line.

•  Fuel in the fuel reserve cup is sectioned out through the fuel filter (low-pressure) by the fuel pump and pumped to the fuel filter (high-pressure). Return fuel is sent back to the fuel reserve cup.

•  Built into the fuel pump unit due to adoption of a returnless fuel system.

•  Mainly consists of a spring and release valve.

•  Pressurizes fuel discharged by the fuel pump to approx. 430 kPa {4.38 kgf/cm², 62.4 psi} using the spring and release valve, and then pumps it to the fuel distributor.

•  If fuel pressure exceeds approx. 430 kPa {4.38 kgf/cm², 62.4 psi}, the release valve opens to discharge unnecessary fuel pressure.
