Fuel Rail: Installation

Remove and discard the fuel injector O-rings. Remove and discard the fuel injector support rings.

• 1.
  
  Pull the lower Teflon ® seal away from the injector.

• 2.
  
  Carefully cut and discard the lower fuel injector Teflon ® seals.

• 1.
  
  Install the Arbor onto the fuel injector tips. Use Special Service Tool: 310-207 Installer, Fuel Injector Seal Assembly.

• 2.
  
  
  NOTE: Once the Teflon ® seal is installed on the Teflon ® Seal Guide, it should immediately be installed onto the fuel injector to avoid excessive expansion of the Teflon ® seal.
  NOTE: Make sure that new lower fuel injector Teflon ® seals are installed.

  Install the new Teflon ® seals onto the Arbor, using the Pusher Tool slide the Teflon ® seals along the Arbor.

• 3.
  
  Using the Pusher Tool, slide the Teflon ® seals off of the Teflon ® Seal Guide and into the groove on the fuel injectors. Use Special Service Tool: 310-207 Installer, Fuel Injector Seal Assembly.

• 1.
  
  Massage and warm the Teflon ® seal with your fingers before the Teflon ® seal sizer tool is installed. This will aid in installing the Teflon ® seal sizer tool.

• 2.
  
  Position the Teflon ® seal sizer tool with the larger opening towards the Teflon ® seal. Push while turning the Teflon ® seal sizer tool 180 degrees. Use Special Service Tool: 303-1567 Sizer, Teflon Seal.

• 3.
  
  Once the Teflon ® seal sizer tool is installed, check and make sure the Teflon ® seal is in the sizing portion of the Teflon ® seal sizer tool.

• 4.
  
  After one minute, turn the Teflon ® seal sizer tool back 180 degrees and remove the Teflon ® seal sizer tool.

• 1.
  
  Install the new the fuel injector support rings.

• 2.
  
  Install the new fuel injector O-rings and lubricate with clean engine oil.

  Install the new the fuel injector clips.

Install the fuel injectors to the fuel rail. Refer to: Fuel Rail Pressure (FRP) Sensor .

Install the fuel rail, push down on the fuel rail above the fuel injectors. Install and tighten the fuel rail bolts in the following 2 stages and in the sequence shown.

Torque:

Stage 1: 44 lb.in (5 Nm)

Stage 2: 17 lb.ft (23 Nm)

• NOTE: Only tighten the 2 high pressure fuel tube flare nuts finger tight at this stage.

  Make sure that a new high pressure fuel tube is installed.

  Calculate the correct torque wrench setting for the following torque using the Torque Wrench Adapter Formulas in the chart below. Install the new high-pressure fuel tube, then tighten the high-pressure fuel tube flare nuts in the following 3 stages.

  Torque:

  Stage 1: 15 lb.ft (21 Nm)

  Stage 2: Wait 5min

  Stage 3: 15 lb.ft (21 Nm)
