SERIES 60 SEA PRO 150/300 DIESEL FUEL PROCESSOR SYSTEM (MARINE)

The Sea Pro 150 fuel processor system (recommended by DDC) consists of a primary fuel processor assembly secured to a mounting plate with two U-bolts, washers, and nuts. The Sea Pro 300 diesel fuel processor system consists of two primary fuel processor assemblies secured to a mounting plate with four U-bolts, washers, and nuts. Each processor assembly consists of a replaceable spin-on filter element assembly with a vent cap, seal ring, and reusable element splash guard. Each processor also has a water-in-fuel (WIF) switch that requires an optional module for activation. The Sea Pro 150 and 300 systems may also include an optional electric primer pump. See Figure 36022 for the Sea Pro 150 and see Figure 36023 for the Sea Pro 300. The Sea Pro system is installed between the fuel tank and the fuel pump. ‪

Removal of the Sea Pro 150 or 300 Fuel Filter Element

Detroit Diesel recommends shutting down the engine and allowing it to cool to engine room temperature before replacing fuel filter elements. ‪

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. Close fuel inlet and outlet valves on the fuel processor. If changing a Sea Pro 300 filter "on the run", open the fuel manifold inlet and outlet valve of the new filter before closing the inlet and outlet valve of the used filter.

    Note: On some Sea Pro 300 models this is accomplished by moving the selector valve lever on the fuel manifold to the "Service Right Can" or "Service Left Can" position.

  2. Open the vent plug on top of the element being serviced, place a suitable container under the processor, and remove the drain valve plug (if installed). Open the bottom valve and allow about a pint of fuel to drain out.

    Note: This will help drain the filter element of fuel.

    Note: Dispose of the used element in an environmentally friendly manner, according to state and federal (EPA) recommendations.

  3. Close the valve, and install the valve drain plug.

    NOTICE:

    The center hole of the processor is the clean fuel outlet to the cylinder head. To avoid possible contamination of the clean fuel, cover the top of the processor with a clean cloth immediately after the filter element is removed. ‪

  4. Using a suitable strap-type filter wrench, rotate the filter element counterclockwise, and spin it off the fuel processor body.

    Note: Any fuel left in the filter element will be caught by the deep well in which the element sits and will drain back into the fuel processor.

  5. Remove the reusable plastic splash seal from the element and retain for reuse.

    Note: Dispose of the used element in an environmentally friendly manner, according to state and federal (EPA) recommendations.

Inspection of the Sea Pro 150 or 300 Fuel Processor

Inspection the Sea Pro 150 or 300 as follows: ‪

  1. Inspect the fuel processors for worn, damaged, or leaky fittings.
    1. If damage was found, replace the component.
    2. If no damage was found, reuse the component.
  2. Inspect threaded inlet and outlet ports on the fuel processors and fuel manifold for damage.
    1. If damage was found, replace the component.
    2. If no damage was found, reuse the component.

Installation of the Sea Pro 150 or 300 Filter Element

Install the Sea Pro 150 or 300 filter element as follows: ‪

  1. Check the new spin-on element to ensure the O-ring seal is just inside the center opening and the perimeter seal is installed at the base.

    Note: Do not install the element if either seal is missing, since this will result in fuel leakage.

    NOTICE:

    Do not use a strap wrench or other tool to tighten the element. Over-tightening may result in filter element or fuel processor damage or both. ‪

  2. Wipe the perimeter seal contact surface on top of the processor with a clean cloth.
  3. Using clean engine oil, lubricate the center O-ring and perimeter seal.
  4. Install the element onto the processor center stud by pressing down, on the element and rotating clockwise to engage the threads. Tighten by hand only.
  5. Install the plastic splash guard onto the element and push down until firmly seated over the fuel processor well.

    NOTICE:

    Do not use a tool to tighten the vent plug. Over-tightening may result in vent plug or fuel processor damage or both. ‪

  6. If the fuel processor assembly is not equipped with a fuel primer pump, remove the vent plug at the top of the filter and fill the element with clean fuel. Replace the plug and tighten by hand only.
  7. If the processor is equipped with a fuel primer pump, prime the system as follows:
    1. Remove the vent on the filter.
    2. Turn the fuel flow valve to "Prime System".
    3. Push the momentary switch mounted above primer pump until fuel is visible in the sight glass on the processor body.
    4. Continue to push switch for an additional 5 to 10 seconds to fill the filter.
    5. Replace vent on the filter and tighten by hand until secure.
  8. Open fuel inlet and outlet valves on the fuel processor manifold. If equipped, put primer pump selector valve in the "Run Position".

    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.
  9. Start the engine and check for leaks.
