  Q: How to service and repair the fuel rail on Ford Ranger?

  A:

  Service and repair procedures for the fuel rail start with disconnecting the battery ground cable while releasing fuel pressure. To start service and repair of the fuel rail begin by first taking off the upper intake manifold and unfastening both the six Fuel Injector electrical connectors and fuel supply tube spring lock coupling. Start by removing the four fuel rail bolts which permits removal of the fuel rail combined with fuel injectors as a set before uncoupling six fuel injectors from the fuel rail and discarding the previous O-ring seals. Proceed with O-ring seal installation by applying engine oil to them and subsequently installing them onto fuel injectors before mounting the injectors to the fuel rail. You should connect the fuel rail along with fuel injectors as one assembly then tighten its four bolts to 10 Nm torque (89 lb-in torque). After connecting the fuel supply tube spring lock coupling and six fuel injector electrical connectors you should install the upper intake manifold before completing the process by reconnecting the battery ground cable.

  Q: How to Maintain the Fuel Rail on a Ford Ranger?

  A:

  You should disconnect the battery ground cable while you remove the fuel pressure before starting fuel rail servicing. Initiate service of the fuel rail by separating the four Fuel Injector electrical connectors with the fuel injector harness from the fuel rail. Thoroughly disconnect the spring lock coupling which maintains the fuel supply tube. You should take apart the fuel rail with its fuel injector components by pulling off both retaining bolts while maintaining their unit support. Static torque of 25 Nm (18 lb-ft) applies when installing the bolts. The fuel rail requires service after you remove its retaining clips which separate the fuel injectors from the fuel rail and eliminate the old fuel injector O-ring seals. The installation requires fuel-resistant seals instead of regular O-rings to avoid leaks in the fuel system because old seals cannot be reused. Engine oil lubrication of the new O-ring seals needs to occur before you reinstall them using the reverse order of removal steps until the fuel injectors have the new seals positioned correctly.
