REMOVAL & INSTALLATION



See Figures 1 and 2


CAUTION
Observe all applicable safety precautions when working around fuel. Whenever servicing the fuel system, always work in a well ventilated area. Do not allow fuel spray or vapors to come in contact with a spark or open flame. Keep a dry chemical fire extinguisher near the work area. Always keep fuel in a container specifically designed for fuel storage; also, always properly seal fuel containers to avoid the possibility of fire or explosion.

There are 2 types of fittings used on fuel filter connections. The banjo fitting or union bolt type uses a bolt and 2 washers to prevent leakage between an eyelet and the filter. The flare fitting type uses no washers or bolts. It uses a thread interference pattern to make a tight connection.

  1. Unbolt the retaining screws and remove the protective shield (if equipped) for the fuel filter.
  2.  
  3. Place a pan under the delivery pipe (large connection) to catch the dripping fuel and SLOWLY loosen the banjo fitting bolt or flare fitting at the bottom of the filter to bleed off the fuel pressure.

CAUTION
To avoid personal injury, remember that the fuel system is under pressure. Release pressure slowly and contain spillage. Wear eye protection and observe no smoking/no open flame precautions. Have a dry powder fire extinguisher within arm's reach at all times.

  1. Remove the banjo bolt or flare fitting and drain the remaining fuel.
  2.  
  3. Disconnect and plug the inlet line.
  4.  
  5. Unbolt and carefully remove the fuel filter. It may still contain some fuel.
  6.  

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 sufficient clearance between the fuel filter, lines and any other parts.

  1. Coat the flare or banjo bolt threads along with the copper washers lightly with engine oil. Always use new washers.
  2.  
  3. Hand tighten the inlet line to the fuel filter.
  4.  
  5. Install the fuel filter then tighten the banjo type bolt to 22 ft. lbs. (29 Nm) or the flare fitting on the fuel pump side to 17 ft. lbs. (24 Nm) and all others to 22 ft. lbs. (30 Nm).
  6.  


WARNING
The fuel pump builds high pressure within the lines. If new gaskets are not used, a high-pressure leak may spray fuel onto the engine or other hot surface.

  1. Run the engine for a few minutes and check for any fuel leaks.
  2.  
  3. Install the protective shield if removed.
