Fuel Tank Cleaning And Flushing
IMPORTANT: Diesel fuel should not be left in tank during winter storage, as an
accumulation of rust, sludge, and wax residue will form.
Refer to boat manufacturer’s instructions and clean fuel tank at specified intervals. Unless
specified otherwise, flush and clean diesel fuel tank every 1000 hours or 5 years, whichever
occurs first.
