1105012D50D2 Diesel Fuel Filter is a high-efficiency fuel purification cartridge for JAC HFC1040 light truck fuel supply circuit. It adopts hydrophobic coalescing filter media to capture rust, sludge and fine solid contaminants in diesel, while separating free water mixed in fuel to protect precision fuel injectors and transfer pump. This aftermarket replacement filter resolves insufficient fuel delivery, power drop under climbing load and nozzle corrosion caused by filter clogging, medium damage and accumulated standing water. Reliable fuel filtration stabilizes injection pressure and reduces engine stalling risk for JAC light trucks running frequent short-haul and city delivery routes.
Product Advantages Multi-layer composite filter paper features high dirt holding capacity and stable water separation performance. Reinforced internal support frame prevents element collapse under fluctuating fuel pressure. Integrated sealing structure avoids bypass leakage under long-time vibration. Every filter undergoes sealing and flow inspection before shipment, OEM thread and gasket support quick spin-on installation during regular maintenance.

FAQ
Q1: What is the main reason for draining water regularly on this fuel filter?
A1: Water builds up at the bottom, eroding injector nozzles and degrading fuel atomization.
Q2: What will happen if air is not bled after installing the new filter?
A2: Air pockets lead to hard starting, rough idle and unstable power output under load.
Q3: How can we identify a clogged fuel filter during road inspection?
A3: Engine power drops obviously when uphill, and fuel pressure reading fluctuates greatly.
