2003 Ford Focus Fuel Rail Parts Q&A

• Q: How to service the fuel rail on 2003 Ford Focus?

  A: The procedure to service the fuel rail starts with releasing fuel system pressure followed by disconnecting the battery cable. You should disconnect the vehicle speed control cable by taking off the inner cable from the throttle body while also detaching the cable from the throttle body. The accelerator cable needs disconnecting through two steps which begin with removing the retaining clip followed by disconnecting the inner cable from the throttle body then rotating the remaining outer cable. First detach the air cleaner outlet tube followed by disconnecting both the fuel pressure sensor electrical connector and the vacuum line connected to the fuel pressure sensor and fuel pulse damper. Before moving on to the fuel injection supply manifold removal you must first disconnect both supply lines of the fuel injection supply manifold along with the injector electrical connectors. The first action requires removing fuel injectors from the fuel injection supply manifold by moving the clip and eliminating each injector followed by discarding the old fuel injector O-ring seals. Install by following the removal procedures backward while applying clean engine oil to the new fuel injector O-ring seals to make installation easier without using silicone grease because it may block the fuel injectors. People must follow fuel handling safety procedures at all times because this system contains dangerous flammable vapor traces.
