Fuel injection system description
Fuel system
The fuel delivery system consists of the fuel tank (1), fuel pump (2), fuel filter (3), fuel feed hose (4), fuel delivery pipes (5) including fuel injectors (6) and (7), fuel pressure regulator (8). There is no fuel return hose. The fuel in the fuel tank is pumped up by the fuel pump and pressurized fuel flows into the injectors installed in the fuel delivery pipe. Fuel pressure is regulated by the fuel pressure regulator. As the fuel pressure applied to the fuel injectors (the fuel pressure in the fuel delivery pipe) is always kept at absolute fuel pressure of approx. 294 Kpa (2.9 Kgf/cm2, 41.8 Psi), the fuel is injected into the throttle body in conic dispersion when the injector opens according to the injection signal from the ecm.
The fuel relieved by the fuel pressure regulator flows back to the fuel tank.

Ecm / various sensors
Since each component is a high-precision part, great
care should be taken not to apply any severe impacts
during removal and installation.
Be careful not to touch the electrical terminals of the
electronic parts (ecm, etc.). The static electricity from
