• Q: How to Properly Maintain Fuel Injectors on a 2007 Ford Mustang?

  A: Start fuel injector servicing procedures by emptying the fuel system pressure then disconnecting the battery cable. Begin on the right side by taking out the wiring harness retainer from the valve cover stud bolt then putting it aside to disconnect the three fuel injector electrical connectors. The right side fuel rail supply tube bolts should be removed and reinstalled with a torque specification of 6 Nm (53 lb-in) while working on the fuel injector service. When installing new fuel rail supply tube O-ring seals it is essential to use special fuel-resistant material because standard O-ring seals might cause fuel system leaks thus the old seals must be discarded. You should first secure the right side fuel rail with 23 Nm (17 lb-ft) torque settings prior to removing its two bolts. After doing that you should take off all three fuel injectors from the rail and dispose of their O-ring seals. The worker should detach the vacuum hose and electrical connector for the fuel rail pressure and temperature sensor from the left-hand side before removing the wiring harness retainer from the valve cover stud bolt and placing it aside. Disconnect the three fuel injector electrical connectors then open the left side fuel rail by removing its two supply tube bolts while reinstalling them at 6 Nm of torque (53 lb-in) tension. The installation process requires removal of the left-side fuel rail supply tube O-ring seal before performing the three-step procedure to remove the left side fuel rail bolts at 23 Nm (17 lb-ft) torque then taking off the three fuel injectors along with their O-ring seals. The installation process ends by following the removal steps in reverse while applying engine oil for lubrication to the new O-ring seals before their installation.
