SMALL FITTING FILTER 30 MICRONS 3581760

Function and technical context

This 30 micron Racor fuel filter acts as a precision barrier in the diesel feed circuit of Volvo Penta marine engines, retaining contaminating particles, sediment and emulsified water before they reach the injection pump and injectors. Its filtration threshold of 30 microns positions it at an intermediate level of protection, suitable for marine environments where fuel quality may be compromised by condensation, algae or residue from the tank itself. A saturated or deteriorated fuel filter causes pressure drops in the circuit, difficult starts, progressive loss of power and even unexpected engine stops while sailing. The characteristic red body of the Racor series facilitates quick identification during maintenance checks in machine rooms with limited space.

When to replace this part?

The most common symptoms that indicate that the fuel filter requires replacement are: difficulty starting when cold, jerks or loss of speed under load, excessive black smoke from the exhaust and activation of the low fuel pressure alarm. For marine diesel engines in regular use, it is recommended to replace the Racor filter every 100-200 hours of operation or at the beginning of each boating season, whichever comes first. Changing this component preventively during annual maintenance is the simplest measure to avoid an engine stop at sea, a situation that can entail a towing and repair cost much higher than that of the filter itself.
