Installation location: At the bottommost transparent water collection cup of the fuel coarse filter (oil-water separator), it is assembled with the coarse filter element. It is placed at the first stage of the fuel pipeline (coarse filter), and the one in front of you, BY1000442956, is the rear-stage fine filter. The two together form a complete fuel system front and rear assembly.
1. Collect the separated water: After the diesel is filtered through a coarse filter, the water settles inside this transparent filter cup, allowing for an intuitive observation of the amount of water accumulated;
2. Bottom water drain valve: The bottom is equipped with a drainage screw. When the water reaches the scale line, simply unscrew the drainage valve to prevent water from entering the engine's fuel system;
Material: PC transparent oil-resistant plastic cup body, resistant to diesel corrosion and impact; equipped with heating resistor + water level sensor probe, rubber sealing ring;
• Voltage: 24V (heavy truck standard)
• Interface: threaded top end, manual water release screw at the bottom; side edge has original waterproof wiring plug from the manufacturer;
• Weight: approximately 0.45kg;
• Feature: Visual observation of water level, integrated heating + water level alarm sensor unit
Common faults: The PC cup cracks; the sealing ring ages and leaks oil and water; the heating element burns out; the water level sensor fails; once water leaks in, it will directly damage the common rail fuel injector.
