SERIES 60 FUEL PRO 380/380E FUEL FILTER SYSTEM

The Fuel Pro 380/380E diesel fuel filter system is used in place of a separate spin-on primary fuel filter. See Figure 27324 . This system uses a high efficiency five-micron fuel filter element which requires replacement when the fuel level in the see-through filter cover reaches the top of the element or after one year of service, whichever comes first. ‪

Note: The secondary fuel filter must be changed at regular mile or hour intervals, depending on the engine application. Refer to section .

Fuel Pro 380E Fuel Processor Assembly

The Fuel Pro 380/380E diesel fuel filter system consists of the following: ‪

  • A permanently mounted fuel processor
  • A replaceable five-micron filter element and sealing grommet assembly
  • A filter spring
  • A see-through filter cover and O-ring seal
  • A cover locking collar
  • A cover vent cap and seal

The Fuel Pro 380E system also includes the following: ‪

  • A fuel heater element
  • A thermostat switch
  • A wiring harness

Replacement of Fuel Pro 380E Fuel Filter Element

Replace the Fuel Pro filter element as follows: ‪

FIRE

To avoid injury from fire caused by heated diesel-fuel vapors:

  • Keep those people who are not directly involved in servicing away from the engine.
  • Stop the engine immediately if a fuel leak is detected.
  • Do not smoke or allow open flames when working on an operating engine.
  • Wear adequate protective clothing (face shield, insulated gloves and apron, etc.).
  • To prevent a buildup of potentially volatile vapors, keep the engine area well ventilated during operation.
  1. With the engine shut down and cool, place a suitable container under the fuel processor.
  2. A fuel shutoff valve may be installed on the discharge side of the fuel filter. If installed, turn the handle on the shutoff valve to the closed position (perpendicular to the valve).
  3. Open the drain valve at the base of the fuel processor, and drain the fuel until it is below the level of the filter. Close the drain valve.
  4. Using filter collar wrench, Part No. 23516731 or equivalent, remove the collar by turning counterclockwise. Remove the cover, filter spring, and cover seal ring by lifting straight up and over the filter element. Remove the element from the center stud (fuel outlet pipe) by pulling upward and twisting slightly.

    Note: Current filter elements include an integral sealing grommet. Former filter elements used a separate sealing grommet. If a former element is replaced, ensure the separate sealing grommet is removed from the center stud.

  5. Dispose of the used filter element and grommet in an environmentally responsible manner, according to state and/or federal (EPA) recommendations.

Installation of Fuel Pro 380E Fuel Filter Element

Install the Fuel Pro filter element as follows: ‪

  1. Ensure a sealing grommet is included in the base of the replacement element, then install the element onto the center stud.

    NOTICE:

    Do not use a wrench of any kind to tighten the collar, since this may lead to overtightening which can damage the collar and the cover. ‪

  2. Ensure the filter spring is installed at the top of the cover. If missing, the spring must be replaced to insure proper filter operation. Wipe the cover lip and cover seal clean. After ensuring the seal is properly positioned at the base of the cover, install the cover and collar onto the fuel processor. Tighten the collar by hand until secure.

    NOTICE:

    To avoid cover or vent plug damage, do not use tools to tighten the vent cap. ‪

  3. Remove the vent cap from the top of the cover by turning the cap counterclockwise. Fill the cover full of clean fuel. After ensuring the O-ring seal is installed on the vent cap, reinstall the cap and tighten by hand only .

    PERSONAL INJURY

    Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm.

    • Always start and operate an engine in a well ventilated area.
    • If operating an engine in an enclosed area, vent the exhaust to the outside.
    • Do not modify or tamper with the exhaust system or emission control system.
  4. Open the fuel shutoff valve (if installed) and start the engine. When the lubrication system reaches its normal operating pressure, increase engine speed to high idle for 2 to 3 minutes.

    NOTICE:

    Do not allow the fuel level in the see-thru cover to fall below the top of the collar, since this may lead to interruption of the fuel flow and engine stalling. ‪

  5. After the air is purged and with the engine still running, slowly loosen the vent cap on the filter cover. The fuel level in the cover will start falling. When the fuel level falls to the top of the collar, tighten the vent cap quickly by hand.

    NOTICE:

    Do not use a wrench of any kind to tighten the collar, since this may lead to overtightening which can damage the collar and the cover. ‪

  6. Shut down the engine and hand-tighten the collar again.
  7. Refer to section for the exhaust caution before preceeding. Restart the engine and check for leaks.

    Note: The clear filter cover will not fill completely during engine operation. It will gradually fill over time as the filter medium becomes clogged. The filter element does not require changing until the fuel level has risen to the top of the element, or after one year of service, whichever comes first.

    Note: The secondary fuel filter must be changed at regular mile or hour intervals, depending on the engine application. Refer to section .
