The presence of rust, sand, dust, wax crystals and water in the fuel of an internal combustion engine will cause wear and tear to the gear pump and precision couplings of the injectors in the fuel pump. High quality fuel filters are installed to minimize contaminants in the fuel system.
1) Filtration efficiency: The percentage of particles removed relative to the total number of particles added.
2) Bubble point pressure: The pressure value when the first series of bubbles emerge from the filter element assembly when immersed in test oil.
3) Resistance: Pressure difference between the inlet and outlet of the filter cartridge at the rated flow rate.
Diesel fuel enters the shell through the inlet, penetrates the filter core, and outputs through the outlet. Mechanical impurities and dust are filtered out while water is precipitated.
Replacement Interval: Every 16,000 km for on-road vehicles or 250 hours (6 months) for off-road vehicles. Always drain air from the system after replacement to prevent engine damage.
