5-2 FUEL SYSTEM AND THROTTLE BODYFUEL DELIVERY SYSTEMThe fuel delivery system consists of the fuel tank, fuel pump, fuel filters, fuel feed hose, fuel delivery pipe(including fuel injectors) and fuel pressure regulator. There is no fuel return hose. The fuel in the fuel tank ispumped up by the fuel pump and pressurized fuel flows into the injector installed in the fuel delivery pipe.Fuel pressure is regulated by the fuel pressure regulator. As the fuel pressure applied to the fuel injector (thefuel pressure in the fuel delivery pipe) is always kept at absolute fuel pressure of 300 kPa (3.0 kgf/cm²), thefuel is injected into the throttle body in conic dispersion when the injector opens according to the injectionsignal from the ECM.The fuel relieved by the fuel pressure regulator flows back to the fuel tank.1 Fuel tank 7 Fuel mesh filter (For low pressure)2 Fuel filter (For high pressure) 8 Fuel pump3 Fuel pressure regulator A Before-pressurized fuel4 Fuel delivery pipe B Pressurized fuel5 Fuel injector C Relieved fuel6 Fuel feed hose
