The Mercedes-Benz W124 is a car model manufactured between 1986 and 1995. It comes in various models, including the 400E, which has fuel pumps located on the underside of the car. The fuel line is a crucial component of the fuel system, connecting the fuel tank to the engine and ensuring the smooth flow of fuel. In this context, the question arises of whether the W124 400E fuel line is compatible with the AN6 specification.

What You'll Learn
The W124 fuel pumps are located on the underside of the car
The W124 fuel pump setup typically consists of two pumps in tandem or series, and this is pretty much standard in W124 estates. To access the fuel pump assembly, you will need to get under the car and remove the plastic shield. The assembly usually consists of two or three components: the fuel pump, a fuel filter, and an accumulator (not on later models). The fuel pump is of the immersed type, where the armature is cooled by the fuel itself. Noisy pumps may be worn or suffering from fuel starvation.
When changing the pump or filter, you will need suitable clamps to isolate them from the fuel lines and the tank. This is to prevent petrol from spilling out. Due to the hazards associated with petrol fumes and inflammability, this is not a job for an inexperienced DIYer.
The Bosch pumps are available from Eurp Car Parts if you wish to supply your own parts to the person that fits them. It should take no more than an hour to replace the pump.
Some W124 models have a twin fuel pump system, and it is worth checking if there is any additional work related to the fuel pump (e.g., pressure regulator, pipes) that would be worth doing at the same time.

The W124 is a Mercedes-Benz E-Class (1987-1995)
The W124 is a Mercedes-Benz E-Class range of executive cars produced from 1984 to 1997. The W124 was the first Mercedes-Benz range to be officially titled as the E-Class, although this only occurred in 1993, and the cars were marketed as the E-Class from 1993 to 1995. The W124 replaced the 123 series and was succeeded by the W210 E-Class.
The W124 was built on the same platform as the W124 Sedan, C124 Coupe, A124 Cabriolet, and S124 Wagon. The range included numerous body configurations, with official internal chassis designations varying by body style: saloon (W 124); estate (S 124); coupé (C 124); cabriolet (A 124); limousine (V 124); rolling chassis (F 124); and long-wheelbase rolling chassis (VF 124). The W124 was also the first Mercedes series to be fitted with the iconic 15-hole, flat-faced alloy wheels, nicknamed 'Gullideckel' or 'manhole covers' due to their resemblance to German manhole covers.
The W124 was launched in North America in early November 1985 as a 1986 model and was marketed through the 1995 model year. The W124 was also offered with five-cylinder diesel engines in India from March 1995 through a joint venture with Telco called Mercedes-Benz India. The final batch of W124s was sold as the limited edition 'Masterpiece' in 1995, with additional accessories fitted as standard.
The W124 gained a good reputation for reliability and included models such as the 260E Sedan, 300CE Convertible, 300D 2.5, 400E, and 500E Sedan.

The fuel line upgrade is a direct replacement from the fuel filter
Upgrading your fuel line is a straightforward process that can be done at home, but it is important to be careful and thorough. Before you start, make sure you have good-quality hose clamps from your supplier. It is also important to wear safety glasses and gloves, have a fire extinguisher on hand, and work in a well-ventilated area away from anything that could cause a spark.
To replace the fuel filter, you will need to remove the old filter and install the new one. The older filters typically had a compression nut-type fitting, and it is important not to make the mistake of rounding off the nut on the end of the fuel line. You can do this by simply applying too much slow torque to the fuel line. Soak the fuel line and the nut with a solvent or penetrant, and then use line wrenches to loosen or tighten. Instead of using your biceps, lock your elbows and use your shoulders to rock back and forth in an impact wrench fashion.
Once you have removed the old filter, you can install the new one. Make sure that the O-rings are in good shape and intact. A little bit of oil on the O-ring will help it snap back into place when you change the new filter. You can then snap the new filter into place, making sure you get a firm snap when putting the clips in place. Finally, tighten the hose clamp from the mount, being careful not to strip the gear on the worm drive hose clamp.

The W124 fuel pump has 3 parts: the pump, accumulator and fuel filter
The W124 fuel pump has three parts: the pump, accumulator, and fuel filter. This is in reference to the Mercedes-Benz W124, produced between 1986 and 1995.
The pump is responsible for moving fuel from the tank to the engine, where it can be combusted. The accumulator helps to smooth out the pressure and flow of fuel, ensuring a consistent supply to the engine. The fuel filter, as the name suggests, filters the fuel, removing any contaminants and ensuring that only clean fuel reaches the engine.
Some W124 models have two fuel pumps, and it is important to check your specific vehicle's setup before making any assumptions about the fuel system. If you are experiencing issues with your fuel pump, it is recommended to consult a specialist to determine the correct part or repair kit for your vehicle.
In terms of fuel lines, the AN6 line is mentioned in relation to the W124. The AN6 line is 3/8" in diameter and is likely large enough to handle the pressure from the tank pump. However, it is always best to consult a specialist or mechanic to ensure that your vehicle has the correct parts and that they are installed properly.

The W124 fuel pump is located near the right tire
The W124 is a Mercedes-Benz E-Class model that was manufactured between 1986 and 1995. This model is known to have a twin fuel pump system, with the fuel pump located near the right rear tire.
The fuel pump is an essential component of the fuel system, responsible for transferring fuel from the tank to the engine. Over time, the fuel pump may start to show signs of wear and tear, such as a whining noise or difficulty starting the engine. In such cases, it may be necessary to replace the fuel pump to ensure the car's optimal performance.
Replacing the fuel pump on a W124 can be a relatively straightforward task, even for a novice DIYer. However, it is important to exercise caution when working with fuel systems due to the associated hazards of petrol fumes and inflammability. Before beginning any work, it is crucial to have a thorough understanding of the car's fuel system and to ensure that suitable clamps are used to isolate the fuel lines and tank.
To access the fuel pump on a W124, one must get under the car and remove the plastic shield covering the fuel pump assembly. This assembly typically consists of two or three components: the fuel pump, a fuel filter, and an accumulator (on older models). The fuel pump is of the immersed type, where the armature is cooled by the fuel itself. Noisy pumps can be indicative of wear or fuel starvation, which could be due to several factors.
