2006 Ford Mustang Fuel Rail Parts Q&A

• Q: How to service the fuel rail on 2006 Ford Mustang?

  A: Service procedures for the fuel rail should start with fuel system pressure release followed by disconnecting the battery ground cable. Begin by taking the wiring harness retainer from the valve cover stud bolt to the right side while putting it off to the side. The three fuel injector electrical connectors should then be disconnected from their location. The first step involves taking out the two bolt connections from the right side fuel rail supply tube while tightening these bolts to 6 Nm (53 lb-in) when reinstalling. Using fuel-resistant special material O-ring seals stands as crucial because regular O-ring seals can possibly cause fuel system leaks which requires immediate discard of the old fuel rail supply tube O-ring seal. First discard the O-ring seals from the three fuel injectors in the fuel rail and remove the right side fuel rail secured by two bolts which should be tightened to 23 Nm (17 lb-ft) during installation before extracted fuel injectors. First disconnect the vacuum hose and fuel rail pressure and temperature sensor electrical connector from the left-hand side. Then remove the wiring harness retainer attached to the valve cover stud bolt and place it to the side. Disembark the three fuel injector electric connectors after tightening two fuel rail supply tube bolts from the left side rail up to 6 Nm torque (53 lb-in) during replacement. Before installing replace O-ring seals with resistant fuel variants and eliminate the old seal from the fuel rail supply tube while tightening left side rail bolts to 23 Nm (17 lb-ft). Before reinstalling discard all existing O-ring seals from the three fuel injectors which will be removed separately from the fuel rail. The installation ends by performing the reverse order of this procedure yet applying fresh engine oil to new O-ring seals before insertion.
