Fuel filter - effective protection against even the smallest particles; indispensable protection for injection systems.

The main purpose of a diesel filter is to protect the injection system and engine against particles, water and other residue in the fuel. Durable seal and housing materials, optimum filter media and improved water separation all make diesel filters from Bosch the ideal solution for your car – even when running on biodiesel.

For gasoline systems, even minute particles can cause serious wear in the electronic injection system and engine of your car. To ensure optimum operation and a long component service life, Bosch gasoline filters can even remove impurities of less than one thousandth of a millimeter in size from the fuel. In carburetor engines, use is made of gasoline line filters to prevent starting problems and rough engine running. These stop the nozzles becoming contaminated.

Bosch Fuel Filters help to protect the most expensive parts of the engine by filtering out foreign particles that can damage a fuel injector. A damaged fuel filter can result in erratic performance, poor gas mileage and in some cases, complete engine shutdown. Even the smallest particles can cause considerable wear and tear to an engine. Protecting the fuel system and the engine from harmful particles, helps to prolong the life of your vehicle. Ensure dependable and trouble-free performance with a Bosch Fuel Filter.

Frequently Asked Questions

1. What is the difference between an Inline Fuel Filter and a Cartridge Fuel Filter?
 

Bosch engineers two types of fuel filters, depending on the type of vehicle being serviced. Consult vehicle owner‘s manual before you change your fuel filter to ensure the correct one is chosen.

  • Inline Fuel Filter - These fuel filters are positioned between the fuel tank, fuel injectors and the fuel line. Various connections (dependent on the filter) are attached or are designed to trap and hold particles from entering the fuel system and engine.
  • Cartridge Fuel Filter - A cartridge-style fuel filter is positioned inside a protective housing of the fuel system. Depending on the application, this housing can be positioned anywhere from the fuel pump or near the fuel tank. The filter media pleats are exposed and used to trap and hold harmful particles.
2. How does a Bosch Diesel Fuel Filter prolong the life of my engine?
 

The Diesel fuel filter protects the injection system and the engine against particles such as water, dirt and other residue in the fuel that can be harmful for the important components of the fuel system. To ensure engine protection, Bosch Diesel Fuel Filters filter down to as low as 6.5 microns* which means Bosch Diesel Fuel Filters will help prolong the life of the engine.
