Fuel Pump Module Assembly

The Mercedes-Benz MB1664701794 is a genuine fuel pump module assembly, serving as a direct replacement for the original equipment. This component is crucial for transferring fuel from the tank to the engine and maintaining the necessary pressure for the vehicle's fuel injection system. It may be situated either inline between the fuel tank and the engine, or internally within the fuel tank itself, and can include an integrated fuel filter and fuel level sensor. Signs of a failing fuel pump include a vehicle that will not start, rough idling, stalling, engine surging, or a severe lack of power. A strong fuel smell within the cabin could indicate a cracked fuel pump housing, leading to fuel vapor leaks. This fuel pump module assembly is compatible with a wide range of Mercedes-Benz models, including the GL450 (2013-2016), GL550 (2014-2016), GL63 AMG (2013-2016), GLE350 (2016-2018), GLE400 (2016-2019), GLE43 AMG (2017-2019), GLE450 AMG (2016), GLE63 AMG (2016-2019), GLE63 AMG S (2016-2019), GLS450 (2017-2019), GLS550 (2017-2019), GLS63 AMG (2017-2019), ML350 (2013-2015), ML400 (2015), ML550 (2012-2014), ML63 AMG (2012-2015), and R350 (2012). However, it is explicitly stated that this part is NOT for cars that use Ethanol Fuel (Code 929), including certain GLE350, GLE400, GLE43 AMG, GLE450 AMG, ML350, and ML350 AWD/RWD models. When replacing the fuel pump, it is highly recommended to also replace the fuel filter or fuel pickup screen to prevent contaminants from damaging the new pump. Some installations may require proof of professional installation for warranty purposes.
