About this Fuel Pump

The BOSCH 18052 fuel pump moves fuel from the tank to the engine at the pressure the fuel-injection system needs. Most modern European cars use an electric pump mounted inside the fuel tank, often as part of a module with the fuel-level sender and a strainer.

Frequently asked questions

What does a fuel pump do?

It draws fuel from the tank and delivers it to the engine at the pressure the injection system requires. If pressure drops, the engine can run lean, lose power or fail to start.

What are the signs of a failing fuel pump?

Long cranking before the engine starts, hesitation or loss of power under load, stalling, a whining or buzzing noise from the tank, or a no-start. A clogged filter, a failed relay or a wiring fault can cause the same symptoms, so check fuel pressure before replacing the pump.

Can I replace a fuel pump myself?

On many cars the pump is reached through an access panel under the rear seat or trunk floor; on others the tank has to be lowered. Relieve the fuel system pressure, disconnect the battery, work in a well-ventilated area away from sparks and flames, and fit a new seal or O-ring at the pump flange. If you are unsure, have a professional install it.

What should I replace along with the fuel pump?

Replace the tank seal or O-ring and, if your car has a separate one, the fuel filter. Inspect the strainer and the electrical connector. If the old pump failed because of dirt or debris, clean the tank before fitting the new pump.

How do I make sure this pump fits my car?

Compare the part numbers listed on this page with the number on your old pump or in your vehicle's parts catalog, and check the fitment information. If you are unsure, contact us with your VIN before ordering.
