This fuel filter kit includes not only the upgraded filter element but also the bracket, all mounting bolts, sealing washers, hollow bolts, pipe joints, and fuel hoses. Everything needed to replace the entire fuel filtration and supply system on the MC13 engine.
The upgraded filter element captures particles down to 5 microns and separates water effectively. It protects the high‑pressure injection pump and injectors from abrasive contaminants, extending their service life significantly.
All bolts are grade 10.9 with MAN183 quality mark, ensuring secure mounting. Composite sealing washers use FPM/FKM rubber for fuel and heat resistance, preventing leaks. The hollow bolts are precision machined for correct flow.
This kit includes all necessary fuel pipes: from tank to filter, filter to high‑pressure pump, and return lines. The rubber hoses are fuel‑resistant and reinforced. Steel pipes are pre‑bent for exact fitment on the MC13 engine.
The fuel filter is mounted on the engine block using the supplied bracket and bolts. Fuel is drawn from the tank by the electric priming pump or delivery pump. It enters the filter through the hollow bolt and composite sealing washers. Inside the filter head, fuel passes through the upgraded filter element, which traps solid contaminants and separates water.
Clean fuel then exits the filter through another hollow bolt and travels to the high‑pressure pump via the steel pipe and rubber hose. Excess fuel from the injectors returns to the tank through the oil return pipe. The system also includes a pressure‑limiting valve return line. Proper installation of this fuel filter kit ensures that only clean, dry fuel reaches the expensive Common Rail injection system.
Before installation, disconnect the battery and relieve fuel pressure. Remove the old filter and bracket. Install the new fuel filter bracket using the M8x40 bolts (25 Nm). Attach the filter head to the bracket using the M6 toothed bolts (10 Nm).
Install the new filter element with a fresh ring joint. Connect the fuel supply line using the hollow bolt M14 and composite washers (torque 25 Nm). Connect the outlet line using the second hollow bolt and washers. Install the steel pipe and secure it with the fixing clamps. Connect the rubber hoses using the pipe joints and buckle clamps. Install the oil return pipes. Prime the system and check for leaks. Start the engine and verify no fuel leaks are present.
This fuel filter kit is specifically designed for the MC13 engine used in the HOWO MAX 4X2 tractor. It fits all production years from 2018 onward. The filter element has the correct thread (M16x1.5) and sealing ring diameter. The bracket matches the existing mounting holes on the engine block. The fuel lines are pre‑formed to clear the turbocharger and exhaust manifold. Always verify your engine serial number before ordering this fuel filter kit.
Inspect the fuel filter for leaks every 10,000 km. Replace the filter element at every scheduled service (typically 30,000 km). Always replace the composite sealing washers when disconnecting any hollow bolt. The ring joint should also be replaced with each filter change. Clean the bracket and inspect for rust. The rubber hoses should be checked for cracking or bulging; replace if damaged. Using a genuine HOWO fuel filter ensures proper filtration efficiency and prevents injector damage.
If the engine lacks power or runs rough, a clogged fuel filter may be the cause. Check the filter element and replace if dirty. If there is fuel leakage around the filter head, the composite sealing washers may be damaged or the hollow bolt may be loose. Retorque to 25 Nm. If air bubbles appear in the fuel return line, there may be a loose connection on the suction side. Inspect all clamps and seals. If the filter bowl shows water, drain immediately. A contaminated fuel system can lead to injector failure. Always use genuine HOWO parts for repairs.
Aftermarket fuel filters often use lower grade filter media that does not achieve the claimed micron rating. Generic bolts may be class 8.8 instead of 10.9, leading to loosening. Composite sealing washers from copy kits may be made from NBR instead of FPM, which hardens with heat and leaks. The fuel hoses may not be rated for diesel or may swell.
Genuine HOWO fuel filter components are manufactured to the exact specifications of the original MC13 engine, using certified filter media, high‑grade fasteners, and fuel‑resistant seals. The small additional cost is far outweighed by the cost of replacing a set of Common Rail injectors.
The fuel filter kit is shipped in a reinforced cardboard box with foam inserts. The hoses are coiled without kinking. The fasteners are in sealed poly bags. The packaging is recyclable. The manufacturing facility is ISO 14001 certified. No hazardous substances are used in the production of these components.
This fuel filter kit includes all 32 line items listed in the parameters table. Individual components can be ordered separately using their material encodings. Authorized HOWO dealers in Nigeria stock these genuine parts. For fleet orders of five or more complete kits, volume discounts are available. Always provide your engine serial number to confirm compatibility.
Fleet managers who have installed this genuine HOWO fuel filter kit report fewer injector failures and longer filter life. The upgraded element has eliminated the hand primer pump issues common with older designs. The complete set of hoses and clamps has simplified installation, saving workshop time. Many operators have standardized on this fuel filter kit for all MC13 engine overhauls, citing the all‑in‑one convenience and the reliability of genuine components.
The fuel filter kit is shipped in a box measuring 60cm x 40cm x 30cm, weight 6 kg. Store the kit in a dry indoor area. Do not remove the protective caps from the filter ports until installation. The shelf life of the filter element is three years when stored properly. Protect the rubber hoses from direct sunlight and ozone.
