NOTE:

Replace the fuel line O-ring seals.

NOTE:

Lubricate the fuel line O-ring seals with 5W30 engine oil meeting Ford 
specification WSS-M2C153-G 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
