  2.  
  3. If not done already, disconnect the negative battery cable.
  4.  
  5. If necessary, remove the air intake hose.
  6.  
  7. Disconnect the vacuum hose to the fuel pressure regulator.
  8.

Fig. Fig. 3: Apply a small amount of clean engine oil to each O-ring before installation

  1. Lightly coat the pressure regulator O-rings with clean engine oil. Be careful not to allow engine oil to enter the fuel rail opening.
  2.  
  3. Insert the fuel pressure regulator into the opening of the fuel rail assembly. If the regulator assembly does not insert smoothly, it may be a binding O-ring seal. Pull out the regulator and inspect the O-ring seal(s) for damage.
  4.  
  5. Install the pressure regulator snapring.
  6.  
  7. Attach the fuel pressure regulator vacuum hose.
  8.  
  9. If removed, install the air intake hose.
  10.  
  11. Connect the negative battery cable.

See Figure 4

The fuel pressure regulator is mounted on the left end of the front fuel rail.

  1. Properly relieve the fuel system pressure, as outlined earlier in this section.
  2.  
  3. If necessary for access to the regulator, remove the air cleaner/inlet duct assembly.
  4.  
  5. Remove the vacuum hose from the fuel pressure regulator.
  6.  
  7. Disconnect the fuel return hose from the pressure regulator.
  8.  
  9. Remove the fuel regulator retainer bolts, then remove the fuel regulator from the fuel rail.

Fig. Fig. 4: Lightly coat the new regulator O-ring with clean engine oil before installing it to the fuel rail

To install:
  1. Replace the O-ring on the fuel pressure regulator with a new one and coat it lightly with clean, thin oil.
  2.  
  3. Insert the regulator straight into the rail, then check that it can be rotated freely.
  4.  

If it does not rotate smoothly, remove it and inspect the O-ring for deformation or damage.

  1. When properly installed, align the mounting holes. Install and tighten the retaining bolts to 78 inch lbs. (9 Nm).
  2.  
  3. Connect the fuel return hose to the pressure regulator.
  4.  
  5. Install the vacuum hose to the fuel pressure regulator.
  6.  
  7. If removed, install the air cleaner/inlet duct assembly.
  8.  
  9. Connect the negative battery cable and pressurize the fuel system. Inspect for leaks.
  10.
