Isuzu Trucks Parts And Accessories CLX-222C Fuel Filter Assembly For Isuzu 4JB1

Function (within 200 characters): A complete diesel fuel filter assembly that removes water, dirt, and microscopic contaminants from the fuel before they reach the sensitive high-pressure injection pump and injectors. Protects the common rail system from fatal damage, ensuring reliable starting and optimal engine performance for 4JB1-T1 engines.

Product Description (Detailed): The CLX-222C Fuel Filter Assembly (OEM Numbers: 1117010-44K, 1117011-44K) is a premium-quality, complete fuel filtration unit engineered specifically for the legendary ISUZU 4JB1-T1 2.8L turbo diesel engine, the workhorse powering millions of light trucks, pickups, SUVs, and industrial equipment worldwide. This complete assembly replaces both the primary filter housing and the secondary filter element, serving as the first line of defense for the common rail fuel system. Its integrated water separator traps and collects moisture that condenses in the fuel tank, while the high-density filter media removes abrasive particles as small as 10–20 microns. Clean, water‑free fuel is the single most important factor for long‑term durability and performance of the 4JB1‑T1 engine. This direct replacement housing is constructed from high‑strength, corrosion‑resistant materials, and it features an integrated manual priming pump for fast, tool‑free air bleeding after filter changes. All sealing O‑rings and gaskets are included for a leak‑proof installation.

A failing or clogged fuel filter assembly — one that is cracked, has a failed primer pump, or a leaking water drain valve — will allow air to be drawn into the system instead of fuel. This leads to hard starting after sitting, rough idle, power loss under load, and, most damaging of all, abrasive particles and water reaching the high‑pressure injection pump, causing its premature and very expensive failure. For a high‑mileage Isuzu 4JB1‑T1, replacing the entire filter housing during major service intervals is standard preventive maintenance. Whether you are performing routine filter service, addressing a no‑start condition after running out of fuel, or replacing a damaged housing, this OE-quality fuel filter assembly is the direct‑fit solution to restore proper fuel filtration, reliable starting, and maximum injection system protection.

• OE Quality: Manufactured to strict ISUZU OEM dimensional and material standards for a perfect, direct‑fit replacement — no modifications, adapter fittings, or custom brackets required. All O‑ring sealing surfaces and port threads are verified against OE blueprints.

• Integrated Water Separator: The built‑in water separator bowl traps moisture before it can reach the high‑pressure injection pump (CP3 pump). A drain valve at the base allows easy, routine draining of collected water, preventing injector corrosion and pump seizure. Water in diesel is the number one killer of common‑rail injectors.

• Integral Manual Priming Pump: The hand‑operated primer pump allows you to quickly and easily prime the fuel system after filter changes or running out of fuel — without repeatedly cranking the starter and damaging the battery or starter motor. A simple plunger, a few pumps, and the system is ready to start.

• Direct Replacement: Simple bolt‑in installation — matches factory mounting holes, fuel line ports (inlet and outlet), and water sensor bung (where equipped) with no modifications required.

• Corrosion‑Resistant Construction: High‑strength, corrosion‑resistant housing materials (composite and metal) withstand diesel fuel, biodiesel blends, road salts, and temperature extremes — ensuring long‑term, leak‑free service life.

• Restores Fuel Flow: Replaces a cracked housing, failed primer pump, or leaking drain valve, eliminating air ingress, hard starting, and low fuel pressure faults.

• Prevents Expensive Fuel System Failure: Restoring proper filtration stops abrasive particles and water from destroying the injection pump and injectors — a common cause of major engine repairs on high‑mileage 4JB1‑T1 trucks.

• Serviceable: The reusable housing accepts standard replacement filter cartridges (sold separately) at routine service intervals.

• OEM Cross‑Reference Confirmed: Directly replaces OE numbers 1117010-44K, 1117011-44K, and 8-94369-199-Z and interchanges with CLX‑222, CLX‑222C, FA1416, FS1416, 1117000X-DW36DG-615.

• 12‑Month / 50,000 km Warranty: Backed by manufacturer batch traceability and a comprehensive warranty against material and manufacturing defects.

• Material Verification: Housing materials (composite and metal) tested for fuel resistance, UV stability, and structural integrity. O‑ring seals and gaskets are validated for compatibility with diesel, biodiesel, and coolant.

• Pressure Testing: Each assembly is 100% pressure‑tested at operating pressure (0.5‑1.5 bar / 7‑22 psi) to guarantee no internal or external leakage.

• Primer Pump Function Test: Hand primer is 100% tested for smooth operation, seal integrity, and effective fuel draw — must be able to draw fuel from the tank without air ingress.

• Thread Verification: Inlet and outlet port threads (M20 * 1.5 standard) and water sensor bung threads are gauged against OE specifications.

• Water Separation Efficiency: Sample‑tested to ensure efficient water removal from diesel fuel (≥ 95% separation efficiency at rated flow).

• Dimensional Accuracy: Mounting bolt hole spacing, port locations, and housing dimensions verified against OE blueprints using CMM equipment.

• ISO 9001:2015 / IATF 16949 Certified: Manufacturing facility meets international automotive quality management standards, ensuring consistent, traceable, and reliable output for wholesale commercial fleets.

• Visual Inspection: 100% inspected for molding defects, cracks, surface imperfections, and sealing ring damage.

• Packaged Safely: Sealed in protective packaging to prevent contamination and damage during transit and long‑term storage.

• Individual Packaging: Each assembly is factory‑sealed in protective packaging and boxed with OE‑style part labeling. All O‑rings and gaskets are included.

• Wholesale / Bulk Orders: Available for heavy‑truck parts distributors, engine rebuilders, workshop chains, fleet operators, and international exporters — sold in case packs of 5, 10, 20, 50 units; pallet pricing available for volume orders.

• Customization: Neutral or private‑label retail packaging (including custom barcode labels) is available for volume wholesale orders (minimum order quantity applies). Discuss your branding requirements with our sales team.
