OEM Common Rail Fuel Injector ME226793 0445120076 For Mitsubishi Fuso 4M50 FE120/FE140/FE145/FE145CC/FE180/FG140 — CRI Injector With 24-Month Warranty

✅ Product Description

The Common Rail Fuel Injector with OEM number ME226793 (also listed as ME 226793, 0445120076, 0 445 120 076, 107755-0360, F01G09P1H7) is a verified OEM-grade direct replacement for Mitsubishi Fuso trucks equipped with the 4M50 4.9L diesel engine. Manufactured by stringent OEM specifications , this high-pressure common rail injector is a critical component of the fuel delivery system. It is responsible for precisely atomizing and metering diesel fuel into the combustion chamber under extreme rail pressure, ensuring efficient combustion, optimal power output, and reduced emissions. This is a Genuine injector supplied in original packaging, exactly as offered by your official dealer-4-5.

This injector is widely used in the Mitsubishi Fuso FE cab-over range — including the FE120, FE140, FE145, FE145CC, FE180, and FG140 4×4 models — running the 4M50 common rail engine from 2005 to 2012-4-5. When a Fuso is starting hard, idling rough once warm, smoking, or running a cylinder-balance fault, the injectors are the first thing worth testing-4.

• ✅ Verified OEM Fitment — Confirmed for Mitsubishi Fuso FE120, FE140, FE145, FE145CC, FE180, and FG140 4×4 with 4M50 engines from 2005–2012-4.

• ✅ OEM Cross-Reference Verified — Replaces ME226793, 0445120076, 107755-0360, 1077550360, F01G09P1H7, F01G09P1H7-5.

• ✅ Critical Fuel System Component — Provides precise fuel delivery; failure results in limp mode, hard starting, or cylinder-balance faults.

[Failure Symptoms]
If your fuel injector is failing, you may experience one or more of the following symptoms:

1. Hard Starting / Extended Cranking: Engine takes longer than normal to start, especially when warm — indicates injector leakage or poor spray quality.

2. Rough Idle When Warm: Engine idles roughly once it reaches operating temperature — a common sign of injector wear on the 4M50-4.

3. Excessive Exhaust Smoke: Black smoke under load (incomplete combustion) or white smoke (unburned fuel).

4. Cylinder-Balance Fault: Diagnostic trouble codes indicating one or more cylinders are not contributing equally-4.

5. Loss of Engine Power: Significant reduction in power and acceleration, especially under load.

6. Increased Fuel Consumption: Poor fuel economy due to inefficient combustion.

⚠️ A failing fuel injector can lead to progressive power loss, increased fuel consumption, and potential damage to the high-pressure fuel pump and other injectors — prompt replacement with a quality OEM injector is essential to maintain fuel system integrity and engine reliability.

✅ Vehicle & Engine Compatibility

⚠️ CRITICAL: This fuel injector is designed for the Mitsubishi Fuso 4M50 4.9L diesel engine. Verify your engine serial number before ordering.

Primary Applications:

Cross-Reference Part Number Table:

⚠️ Important:

• This fuel injector is designed for the Mitsubishi Fuso 4M50 4.9L diesel engine.

• Quantity Required: 4 injectors per engine.

• CRITICAL: The 4M50 engine ran more than one injector part number across the FE range and build years, and they are not interchangeable. The 4M50 also ran the 0445120049 — verify your engine serial number before ordering-4.

• CRITICAL: New common rail injectors need coding to the engine. Each injector carries a calibration code that must be written to the ECU for the cylinder it is fitted to, using the correct diagnostic tool-4.

• Please verify your vehicle's chassis code, production year, and engine serial number before ordering.

✅ Features & Benefits

✅ Quality Control & Verification

Our manufacturing and inspection processes ensure every fuel injector meets or exceeds OEM standards.

✅ Installation & Maintenance Recommendations

⚠️ IMPORTANT: Professional Installation Highly Recommended

Common rail injector replacement requires depressurization of the fuel system, extreme cleanliness, and expert knowledge of common rail systems.

Pre-Installation Checklist:

• Depressurize the fuel system before starting work.

• Disconnect the negative battery terminal.

• CRITICAL: Verify your engine serial number — the 4M50 also ran the 0445120049 injector, and the two are not interchangeable-4.

• CRITICAL: The common rail fuel system is highly sensitive to contaminated or poor-quality diesel fuel — always use clean, high-quality fuel and replace the fuel filter simultaneously.

• Clean the area around the injectors to prevent contamination.

• Quantity Required: 4 injectors per engine — replace all four simultaneously for optimal performance.

Installation Guidelines (Reference Mitsubishi Fuso workshop manual):

1. Depressurize the fuel system and disconnect the negative battery terminal.

2. Remove the intake manifold and fuel rail to access the injectors.

3. Disconnect the electrical connectors from each injector.

4. Carefully remove the injector retaining clamps and pull each injector from the cylinder head.

5. Clean the injector bores in the cylinder head thoroughly.

6. CRITICAL: Install new copper gaskets and O-rings on the new injectors.

7. CRITICAL: Lubricate new O-rings with clean diesel fuel before installation.

8. Install the new injectors into the cylinder head.

9. Install the fuel rail and injector clamps.

10. CRITICAL: Torque the injector clamp bolts to manufacturer's specified torque settings (refer to Mitsubishi Fuso workshop manual).

11. Reconnect all electrical connectors.

12. Reconnect the battery and prime the fuel system.

13. CRITICAL: Bleed air from the fuel system thoroughly to remove all air.

14. Start the engine and check for fuel leaks around the injectors.

15. CRITICAL: Code each injector to its respective cylinder using a diagnostic scan tool — new injectors need coding to the engine-4.

16. Clear any diagnostic trouble codes.

Maintenance Schedule:

• Inspection: Every 50,000 km / 12 months. Check for rough idle, misfires, or increased fuel consumption.

• Fuel Filter Replacement: Every 20,000–30,000 km — regular filter changes are the single biggest factor in injector longevity.

• Replacement: Recommended at 200,000–300,000 km or immediately if failure symptoms appear.

• Note: The 4M50 common rail system is highly sensitive to fuel quality — always use clean, high-quality diesel fuel to maximize injector service life.
