The fuel filter is an important component of the engine. Modern high-performance injection systems place high demands on the quality and purity of the fuel. But the fuel often contain particles of dirt and water. Further, the formation of rust in the interior of the steel tank which can engage the fuel into the engine. This can lead to premature wear, to the failure of the fuel pump and injection system. This not only increases fuel economy and reduces engine power, but may clog and the engine to stall. Fuel filters clean the fuel of dirt particles, rust, water and fuel residues, and ensure engine a long life.
Distinguish between diesel filters and petrol filters
Diesel filters usually have a bowl-shaped design. You need to filter more water from the fuel, which they reduce the lubricating effect of diesel. Diesel filters can be heated, so that in very cold not the paraffin in the fuel is filtered out accidentally. And fuel filters are usually incorporated directly into the suction line and are located in a metal or plastic housing.
