- Disconnect the fuel hoses
from the fuel filter/heater element housing.
- Disconnect electrical and vacuum lines from:
• | EGR valve vent solenoid |
• | EGR valve vacuum sensor |
- Remove bolts retaining sensor/bracket assembly.
- Remove the fuel filter bracket-to-valve cover bolts.

Installation Procedure
- Install the fuel filter
to the fuel filter/heater element housing.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the fuel
filter bracket to the fuel filter/heater element housing.
