Mercedes-Benz B-Class W245 M266 Fuel Pump Module | 2005–2011 | B180 B200 Petrol Sender Unit Spares

Description

Restore dependable fuel delivery, optimum line pressure, and flawless engine responsiveness to your vehicle with this premium Mercedes-Benz W245 Fuel Pump Module Assembly (In-Tank Fuel Delivery Unit & Sender). Specifically sourced and verified for the first-generation B-Class (W245 platform) equipped with the M266 4-cylinder petrol engine (found in B150, B170, B180, and B200 models from 2005 to 2011), this complete electronic fuel delivery system is the definitive replacement for an aging or burnt-out electric fuel pump causing engine starvation.

The In-Tank Fuel Pump Module is the heart of your vehicle’s fueling infrastructure, responsible for drawing fuel from the tank and pushing it forward down the line at a constant, factory-regulated pressure of 4 bar. Because the M266 powertrain relies on accurate, continuous fuel volume to maintain correct air-fuel ratios, any drop in pump efficiency will trigger immediate drivability problems. Over time, factors like tank sediment accumulation, running low on fuel repeatedly (which overheats the electric motor), or normal bearing wear cause the pump to degrade. Typical symptoms include extended engine cranking times on cold starts, severe engine hesitation or cutting out under load, a high-pitched whining noise emanating from under the rear seat, or an inaccurate fuel gauge reading on the dashboard cluster. Replacing the entire integrated assembly completely cures these mechanical and electrical delivery faults.

Manufactured using advanced polymers and corrosion-resistant internal metals, this module is built to withstand continuous exposure to modern fuel blends. It arrives as a fully integrated, pre-assembled unit, containing the high-torque electric fuel pump motor, a fine-mesh protective strainer, the internal fuel pressure regulator, and a precision floating arm sender unit to ensure exact dash fuel gauge tracking. Trust TP German Auto Spares for verified, workshop-tested fuel injection components, fuel pumps, and engine management electronics that preserve the premium reliability of your Mercedes-Benz.

Key Features:
