Components:
- Transparent Bowl: Allows visual inspection of fuel and water separation.
- Threaded Connection: For secure attachment to a compatible fuel filter.
- Drain Plug: Located at the bottom for easy removal of collected water.
- Sensor Ports: Designed for integration with fuel/water sensor systems (sensors not included).
- Sealing Gasket/O-ring: Ensures a leak-proof seal between the bowl and the filter.
Installation
- Safety First: Ensure the engine is off and cool. Disconnect the battery to prevent accidental starts. Wear appropriate personal protective equipment (PPE), including gloves and eye protection.
- Prepare the Area: Place a drain pan beneath the fuel filter assembly to catch any spilled fuel.
- Remove Old Bowl (if applicable): Carefully unscrew the existing fuel/water separator bowl from the fuel filter. Be prepared for fuel spillage.
- Inspect and Clean: Inspect the mating surface of the fuel filter for any debris or damage. Clean the surface thoroughly.
- Install New Gasket: Ensure the new sealing gasket (O-ring) is properly seated in the groove of the new Wix WF10136 bowl. Lightly lubricate the gasket with clean diesel fuel or engine oil to aid in sealing and prevent twisting.
- Attach the Bowl: Carefully thread the Wix WF10136 bowl onto the fuel filter. Hand-tighten until snug, then tighten an additional 1/2 to 3/4 turn with an appropriate wrench, following manufacturer's torque specifications if available. Do not overtighten, as this can damage the bowl or gasket.
- Connect Sensors (if applicable): If your system uses fuel/water sensors, carefully transfer them from the old bowl (if present) or install new ones into the designated ports on the WF10136 bowl. Ensure all electrical connections are secure.
- Prime the System: After installation, it is crucial to prime the fuel system according to your vehicle or equipment manufacturer's instructions to remove any air introduced during the process. This may involve cycling the ignition key, using a hand primer pump, or bleeding air from the system.
- Check for Leaks: Start the engine and carefully inspect the area around the new bowl for any fuel leaks. If leaks are detected, shut off the engine immediately and re-check the installation.
Operation
The Wix WF10136 Fuel/Water Separator Bowl operates passively as part of your fuel filtration system. Its primary function is to collect water and heavier contaminants that have been separated from the fuel by the fuel filter element.
Visual Inspection:
Regularly inspect the transparent bowl for the presence of water or sediment. Water will typically appear as a distinct layer at the bottom of the bowl, often with a cloudy or milky appearance, or as visible droplets.
Draining Water:
When water accumulation is observed, it must be drained promptly to prevent it from entering the fuel system and causing damage. Refer to the Maintenance section for draining procedures.
Maintenance
Regular maintenance of the fuel/water separator bowl is essential for optimal engine performance and longevity. The primary maintenance task is draining accumulated water.
Draining Water from the Bowl:
- Engine Off: Ensure the engine is completely shut down and cool before proceeding.
- Prepare for Drainage: Place a suitable container (e.g., a small bucket or pan) beneath the drain plug of the fuel/water separator bowl to collect the drained fluid.
- Open Drain Plug: Slowly open the drain plug located at the bottom of the bowl. For some models, this may be a petcock valve or a threaded plug that needs to be unscrewed.
- Drain Water: Allow the water and any sediment to drain out until clean fuel begins to flow.
- Close Drain Plug: Once clean fuel is observed, close the drain plug securely. Do not overtighten.
- Dispose of Fluid: Properly dispose of the drained fuel/water mixture according to local environmental regulations. Do not pour it onto the ground or into drains.
- Prime System (if necessary): Depending on your fuel system, you may need to prime it after draining to remove any air that entered. Refer to your vehicle or equipment manual for specific priming instructions.
- Check for Leaks: After closing the drain, start the engine and visually inspect the drain plug area for any leaks.
Cleaning the Bowl:
The bowl typically does not require internal cleaning unless significant sediment buildup is observed during a filter change. If cleaning is necessary, remove the bowl as per installation instructions, clean with a suitable fuel system cleaner or clean diesel fuel, and ensure it is completely dry before reinstallation.
Replacement:
The Wix WF10136 bowl is designed for durability. Replace the bowl only if it becomes cracked, damaged, or if the threaded connection or sensor ports are compromised. Always use genuine Wix replacement parts.
