INSTALLATION
NOTE:
^
Install new fuel system O-ring seals using approved O-ring seals only. O-ring seals that are approved for natural gas use are identified with a
yellow stripe.
^
Lubricate the fuel system O-ring seals with Super Premium SAE 5W-20 Motor Oil XO-5W20-QSP or equivalent meeting Ford specification
WSS-M2C153-H or equivalent prior to installation to help seal and ease the installation.
^
When tightening the fuel lines, a torque wrench adapter must be used with the torque wrench. The use of a torque wrench adapter will alter the
effective torque of the torque wrench being used. To correct the effective torque, a torque multiplication conversion must be used.
