Fuel System Leak Detection Pump A0005450141 Replacement
Fuel System Leak Detection Pump A0005450141 Replacement
Fuel System Leak Detection Pump — OEM A0005450141
Keep your vehicle's evaporative emission control (EVAP) system running at peak performance with this precision-engineered replacement leak detection pump. Designed as a direct-fit replacement, this pump generates negative pressure to test the integrity of your fuel tank, carbon canister, fuel lines, and fuel filler cap — helping you diagnose EVAP leaks quickly and accurately.
Key Features
- Accurate EVAP Leak Detection: Establishes controlled negative pressure within the carbon canister and fuel tank pipeline to monitor pressure attenuation and identify fuel vapor leaks in the oil tube, fuel tank, carbon canister, and fuel filler cap.
- Emissions Control Support: Works in cooperation with the carbon canister system to collect volatile fuel vapors, preventing direct air contamination and maintaining proper air pressure balance inside the fuel tank.
- Sealing & Pressure Balance: Helps verify sealing integrity across related lines and works with the EVAP recovery assembly to balance internal fuel system pressure.
- Reduced Downtime: Engineered to minimize common fitment issues such as incorrect model selection, interface mismatches, and post-installation fault codes — reducing time lost to repeated disassembly.
- Restores System Efficiency: Addresses performance degradation caused by worn original components and inefficient EVAP system detection results.
- ABS Construction: Durable ABS material ensures long-lasting performance under demanding under-hood conditions.
Compatible Fault Codes Addressed
- P0442 — Small EVAP System Leak
- P0455 — Large EVAP System Leak
- P031554 — EVAP Leak Detection Pump

Frequently Asked Questions
Q: What OEM part numbers does this fuel system leak detection pump replace?
A: This pump is a direct replacement for OEM part numbers A0005450141, 958906243A, 95860510700, 7L0906243A, and 16137193479, making it suitable for a wide range of compatible Mercedes-Benz and related vehicle classes.
Q: Which vehicle classes is this EVAP leak detection pump compatible with?
A: This replacement leak detection pump is compatible with C, E, S, GLC, GLK, A, CLA, and B Class vehicles that use the listed OEM part numbers. Always verify your specific vehicle's part number before ordering.
Q: How does the fuel system leak detection pump work?
A: The pump creates negative pressure within the EVAP system — including the fuel tank, carbon canister, and fuel lines — and monitors pressure attenuation over time. If pressure drops beyond acceptable limits, the system identifies a fuel vapor leak in the circuit, helping trigger or clear the relevant diagnostic fault codes.
Q: Will this pump clear my Check Engine light caused by EVAP fault codes?
A: If the root cause of EVAP-related fault codes such as P0442 or P0455 is a failed leak detection pump, replacing it with this unit can allow the EVAP system to function correctly, enabling fault codes to clear after successful system diagnostics. Always perform a full system check to confirm the pump is the source of the fault.
