About Secondary Fuel Pump Diesels

The engine is the power machine of a car, literally converting energy, in the form of fuel, into movement, and is known as an internal combustion engine. The engine is made up of several components that all work together to enable combustion to occur and in turn the car to move. The diesel fuel pump functions to pump diesel from the fuel tank into the cylinders of a diesel engine. 

There are two fuel pumps in some fuel injected engines. One fuel pump will be located within the fuel tank and the secondary fuel pump is positioned on or close to the engine itself.

The fuel pump is an electronic device which delivers fuel under high pressure to meet the demands of the fuel injection engine. Working in conjunction with a computerised control unit, the diesel fuel pump and secondary fuel pump work to pump fuel into the engine while ensuring the correct level of pressure is applied to inject the right amount of fuel into the engine at the right time.  The diesel pump works by spraying a light mist of fuel from injectors into the chambers of the engine, controlled by the computerised control unit, which manages the timing of this process. The injectors are fitted close to the inlet manifold, one for each cylinder, and are all calibrated (adjusted) to equally spray a mist of fuel into the intake of each cylinder in a sequence controlled electronically, for the sequential firing of the engine. The overall result of this ensures the engine is working to its optimum, providing more power and fuel efficiency.

An engine that won't start; a misfiring engine; an engine that struggles and stutters at high speeds;  loss of power while accelerating; loss of power when driving uphill; and the vehicle surging or jumping forward when in motion could all be signs of a faulty secondary diesel pump. There are many things that can go wrong in the engine, so it's a good idea to consult with your mechanic to establish the exact cause of the fault before buying replacement parts. Specifically designed for the make and model of your vehicle, the Mercedes-Benz secondary fuel pump diesel is the ideal choice when replacing this part. 

Mercedes-Benz trivia

• That new car smell is always a delight, but a Mercedes owner gets to choose that smell. Perfume specialist Marc vom Ende created four different car smells for Mercedes Benz, called Sports Mood, Freeside Mood, Downtown Mood, and Nightlife Mood. They all smell a bit leathery.
• In 1924, Mercedes Benz became the first car manufacturer to include brakes on all four of a car's wheels. Not long after, in 1931, they also added suspension springs to the corners of the Mercedes Benz 170.
• Most people think of silver when they think of a Mercedes, but that iconic colour was an accident. Just before a race in 1934, the white-painted W25 was found to be 1kg over the weight limit. The paint was quickly removed, the weight limit reached, and the car won the race.
• Unlike most cars, Mercedes vehicles are not spray painted. Instead, they are completely submerged in anti-corrosion coating and primer. That means the protective liquid can get into every part of the car.
• If you thought self-driving cars were all about Tesla, then it might surprise you to know that Mercedes Benz made an autonomously driving vehicle as early as 1995. It didn't gain popularity, but it became the foundation of the modern driving technology found in every Mercedes Benz.
