REMOVAL & INSTALLATION



See Figures 1 through 7

The fuel filter is located under the vehicle on the drivers side near the charcoal canister. Access is much easier from under the vehicle.


CAUTION
Never smoke when working around or near gasoline. Make sure that there are no active ignition sources (heaters, electric motors or fans, welders, anything with sparks or open flame.) in the area. Have a fire extinguisher within arm's reach at all times.

To install:

When tightening the fuel line bolts to the fuel filter, you must use a torque wrench. The tightening torque is very important, as under or over tightening may cause fuel leakage. Insure that there is no fuel line interference and that there is sufficient space between the fuel lines and other components.

  1. Coat the flare unit, union nut and all bolt threads with engine oil.
  2.  
  3. Hand-tighten the inlet line to the fuel filter.
  4.  
  5. Install the fuel filter and then tighten the inlet line nut to 22 ft. lbs. (29 Nm).
  6.  
  7. Reconnect the delivery pipe using new gaskets and then tighten the union bolt to 22 ft. lbs. (29 Nm).
  8.  
  9. Run the engine for a short period and check for any fuel leaks.
  10.  
  11. Install the protective shield if equipped.
