Installation of the Fuel Prefilter

Installation of the Fuel Prefilter - EuroIV Ops

Install the fuel prefilter as follows:

Note: If a filter service is being performed, replace all other filters before priming.
  1. Install a new prefilter cap seal ring on to the prefilter cap.
  2. Snap new prefilter into the prefilter cap.
  3. Apply a thin coat of petroleum-based lithium grease to the prefilter cap seal ring and the prefilter seals (1).
  4. Install the prefilter into the fuel filter module.
  5. Turn the cap counterclockwise until a click sound is made, then turn clockwise and hand tighten.
  6. Torque prefilter cap to 55-60 N·m (41-44 ft·lb).
  7. Once all required filters have been changed, prime the fuel system using the ESOC 350, J-47912 or the engine mounted hand primer.

    8. Warning: ENGINE EXHAUST

    To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area. Engine exhaust is toxic.

    Warning: PERSONAL INJURY

    To avoid injury before starting and running the engine, ensure the vehicle is parked on a level surface, parking brake is set, and the wheels are blocked.

  8. Start the engine with the accelerator pedal in the idle position. Monitor the oil pressure gauge or indicator lamp. Maintain the engine running at idle until a stable oil pressure reading of 97 kPa (14 psi) or more is maintained for one minute.
  9. Check for leaks.
    10. Notice: Increasing engine speed above idle before oil pressure has stabilized may cause severe engine damage.
  10. Allow the engine to reach operating temperature of 60°C (140°F).
  11. Increase engine speed to 1800 rpm for three minutes.
  12. Return the engine to idle and allow to idle for approximately one minute, then shut down the engine.
  13. Check for leaks.
