Most of the mechanics believe that the periodic replacement of auto fuel filter will result in the fuel pump and engine running smoothly. The auto fuel filter is designed to catch particles and impurities in the tank before gasoline reaches the pump; this ensures clean fuel reaches to the engine.
Like any other filter, impurities will clog it up over the time making the fuel pump to work harder, which in turn can result in breaking down. Engines can also be damaged due to contaminated fuel. The auto fuel filters need to be replaced in every 30,000 kms and always go through the user manual to see manufacturer recommended guidelines in regards to the fuel filter replacement.
