Consequences of silted-up filter:

• Loss of engine power, even to the extent of an engine standstill
• Impairment or interruption of the fuel supply
• Impairment to the output of the fuel pump, even to the extent of a short-circuit
• Increased wear
• Internal corrosion of engine components

Also ideal for biodiesel: Bosch diesel filters

Special features of biodiesel:

• Aggressive behavior against elastomers and sealing materials
• "Saponification" of the fuel through reactions with certain materials
• Lower water separation
• Faster silting up of the diesel filter
• Increased growth of microorganisms

Thanks to resistant materials for the seal and housing, ideal filter media, and improved separation of water, diesel filters from Bosch are the optimal solution even when using biodiesel.
