Fuel Pumps for Mercedes-Benz 450SL

Sold from 1973 to 1980, the Mercedes-Benz 450SL has a fuel-injected V-8 engine which means the Mercedes-Benz SL fuel pump works under pressure and uses an electric fuel pump rather than a mechanical fuel pump. With a wide selection of fuel pumps for Mercedes-Benz 450SL, you can find the right one for you vehicle.

What does the fuel pump in a vehicle do?

The fuel pump pulls gas from the gas tank into the engine. The gas is mixed with air and sent to the vehicles cylinders. Excess fuel will return to the gas tank. Because it gets hot, the electric fuel pump in the 450SL is located in the fuel tank, and the fuel keeps it cooler. Also, as an electrical component, it can create sparks. In the gas tank, it is sealed away from more explosive gas vapors.

How do you know if the fuel pump needs replacing?

Some issues that can indicate an issue with your fuel pump are:

  • Your vehicle sputters at high speeds, loses power on hills, or loses power when it is pulling heavy loads.
  • Your car heats up and stalls.
  • The fuel pressure is too low when you check the fuel pressure gauge.
  • Your vehicle has sudden bursts of acceleration.
  • There is a drop in your gas mileage.
  • Your car wont start.
What you should consider when replacing a fuel pump?

Even if you are experiencing any of the issues above, make sure the issue is not the relay, the fuel filter, an electrical problem, or a leak in the fuel line. If you are replacing the fuel pump yourself, take the following safety precautions.

  1. Empty the gas tank using approved gasoline containers.
  2. Have a fire extinguisher ready, and use safety goggles and gloves.
  3. Disconnect the ground (black) battery cable from the negative battery terminal.
  4. Make sure there is adequate ventilation in the area you are working.
  5. Remove anything from your work area that can create a spark.
  6. Follow the instructions in your owners manual to release pressure in the gas tank.
  7. Do not allow dirt to get into the gas tank or the fuel hoses.
  8. When you are done, make sure there are no leaks.
What brands can be used in the Mercedes-Benz 450SL?

For classic cars like the Mercedes SL, high-performance parts are recommended, such as Bosch, Delphi, Beck Arnley, Airtex, and Action Crash. These parts will give you the desired performance from your Mercedes 450SL, and the fuel pump will last a long time. Although, as long as the fuel pump is compatible with your specific model, it won’t matter what brand you choose.
