Fuel filter
All models have a fuel filter in the fuel line before the fuel pump.
NOTE! Volvo Penta EFI engines require a special ma-
rine filter with a 5-10 micron filtering capabil-
ity. Do not substitute any other type of filter.
WARNING!
Accumulation of water and other fuel contaminants
may form corrosive compounds that can damage the
fuel filter, and result in fuel leakage. For this reason,
annual replacement of the fuel filter is required to
avoid risk of explosion or fire.
