Fuel system

A fuel pressure regulator is incorporated onto the outlet of the electric fuel pump to obtain a compact
design and simple fuel delivery.
Fuel discharged from the pressure regulator returns to the vapor separator after being cooled in the
fuel cooler.
The pressure check valve is incorporated onto the fuel rail for easier servicing of the fuel system.
