Description
Maintain dependable fuel delivery and consistent engine performance with the Fuel Pump Module GE246GEN, listed for selected Mercedes-Benz C-Class models from 2000 to 2005, including W203 sedan, S203 estate and C203/CL203 coupe applications. The listed engine capacity range is 2.0 to 3.2 litres, covering selected variants subject to their original fuel system configuration.
The fuel pump module is an important component of a petrol vehicle’s fuel delivery system. It helps transfer fuel from the tank to the engine at the pressure and flow rate required for proper operation. Depending on the vehicle’s design, the module may include an electric fuel pump, fuel strainer, housing, electrical connections and fuel-level sender.
Mercedes-Benz C-Class vehicles are designed to provide a comfortable driving experience, responsive performance and dependable everyday usability. A correctly functioning fuel system is essential to support these characteristics. When the fuel pump module becomes worn, restricted or electrically defective, the vehicle may develop starting difficulties, hesitation, reduced engine power or unexpected stalling.
The GE246GEN fuel pump module is a replacement option for compatible applications. Selecting the correct unit and confirming its specifications before installation can help restore reliable fuel delivery when the original module has been diagnosed as faulty.

Important fitment note: The listed chassis codes cover different C-Class body styles and engine variants. The 2.0L–3.2L range may include both four-cylinder and V6 engines, so the I4 16V description does not apply to every vehicle in the range. Fuel pump module designs may also vary with engine, production date and market.
Before ordering, verify the vehicle identification number (VIN), engine code, production date and original fuel pump part number. Compare the replacement module’s connector, mounting arrangement, fuel line connections and dimensions with the original unit. A suitable parts catalogue or Mercedes-Benz specialist can help confirm the correct application.
What Does a Fuel Pump Module Do?
The fuel pump module supplies fuel from the tank to the engine’s fuel injection system. Its electric pump must provide the pressure and flow rate specified for the particular engine.
When the ignition is switched on, the vehicle’s electrical control system may activate the pump briefly to establish fuel pressure. During engine operation, the pump continues supplying fuel as required for starting, idling, acceleration and cruising.
Depending on the original design, the module may include a fuel strainer to help prevent larger contaminants from entering the pump. It may also incorporate a fuel-level sender, which communicates fuel quantity to the dashboard gauge.
A properly functioning module supports consistent fuel delivery and helps the engine operate smoothly across different driving conditions. If the pump becomes weak or its electrical supply is interrupted, fuel pressure may fall below the required level, affecting engine performance.
Because the Mercedes-Benz C-Class range includes several engine and body configurations, a replacement module must match the original system’s requirements. Differences in pump pressure, flow capacity, electrical connectors and sender design can affect fitment and operation.
Common Signs of a Faulty Fuel Pump Module
Fuel pump problems can develop gradually or occur suddenly. The following symptoms may indicate a fault in the fuel delivery system.
1. Difficulty starting the engine
A weak pump may struggle to establish the required fuel pressure, causing extended cranking or preventing the engine from starting.
2. Hesitation during acceleration
Inconsistent fuel delivery may cause the engine to hesitate, stumble or respond poorly when the accelerator is pressed.
3. Reduced engine power
If the pump cannot supply enough fuel under load, acceleration may become sluggish and engine performance may decline.
4. Intermittent stalling
A failing pump or faulty electrical connection may interrupt fuel delivery and cause the engine to stall unexpectedly.
5. Unusual fuel tank noise
A louder-than-normal whining or buzzing sound may indicate a pump problem. However, some pump noise is normal, and low fuel levels or fuel system restrictions may also contribute.
6. Incorrect fuel gauge readings
If the module includes a fuel-level sender, a fault in the sender or its wiring may cause inaccurate dashboard readings. This does not necessarily mean the pump itself has failed.
These symptoms can also be caused by a defective relay, damaged wiring, clogged strainer, ignition problem or faulty engine sensor. A proper diagnosis should be completed before replacing the module.
Benefits of Replacing a Faulty Fuel Pump Module
When the original module has been confirmed as defective, installing a compatible replacement can help restore normal fuel delivery.
- Reliable engine starting: Correct fuel pressure supports dependable starting.
- Consistent fuel supply: A suitable pump helps deliver the fuel required by the engine.
- Smoother acceleration: Restoring adequate fuel delivery may resolve hesitation caused by a failing pump.
- More consistent performance: Correct fuel delivery supports normal engine operation during daily driving.
- Reduced risk of fuel-related breakdowns: Replacing a confirmed faulty module can help prevent interruptions caused by failing fuel delivery.
- Fuel gauge functionality: If the replacement includes a compatible sender, it may help restore accurate fuel readings when the original sender is defective.
- Convenient parts identification: The GE246GEN reference provides a starting point for matching the replacement to the original component.
Actual results depend on the condition of the entire fuel system and whether the pump module is responsible for the vehicle’s symptoms. Replacing it will not resolve unrelated engine, ignition or electrical problems.
Installation and Maintenance Recommendations
Fuel pump module replacement involves petrol and electrical components. Installation should be carried out by a qualified mechanic familiar with Mercedes-Benz fuel systems and the manufacturer’s service procedures.
Before servicing, the fuel system must be depressurised correctly, and ignition sources must be kept away from the work area. Appropriate ventilation and precautions against fuel spills are essential.
During installation, inspect the electrical connectors, wiring, fuel hoses, seals and mounting components. Replace damaged seals and repair defective connections where necessary. Ensure the module is correctly seated and all fuel lines are securely connected.
After installation, check for fuel leaks and confirm that the pump operates correctly. Where required, test fuel pressure against the manufacturer’s specifications. If the original complaint involved incorrect fuel gauge readings, check the sender and dashboard gauge operation.
Keeping the fuel system clean and investigating starting or performance problems promptly can help reduce unnecessary repairs.
Important Fitment Information
The GE246GEN Fuel Pump Module is listed for selected Mercedes-Benz C203, W203, CL203 and S203 applications from 2000 to 2005. However, the broad engine range and differences between body styles make individual fitment verification essential.
Before purchasing, confirm the VIN, production date, engine code, original part number, connector design and module configuration. Check whether the replacement includes the fuel-level sender and other components required by the original assembly.
Conclusion
The Fuel Pump Module GE246GEN is a replacement option for selected Mercedes-Benz C-Class applications. As a key component of the fuel delivery system, it helps supply the fuel required for dependable starting and consistent engine operation.
For the best results, diagnose the original fault, confirm compatibility with the exact vehicle and ensure correct installation. Selecting the appropriate replacement can help restore reliable fuel delivery and support the everyday performance of your Mercedes-Benz C-Class.
