Fuel Supply System

System Description

The fuel supply system consists of a fuel tank, in-tank

high pressure fuel pump, PGM-FI main relay, fuel filter,

fuel pressure regulator, fuel injectors, and fuel delivery

and return lines. This system delivers pressure-regulat-

ed fuel to the fuel injectors and cuts the fuel delivery

when the engine is not running.
