Engine Fueling System__________________________
Your fuel system requires inspection with each trip, along with yearly
inspection and maintenance.
To inspect your fuel lines, all lines need to be visually inspected
for cracks, melting, crimped spots, and leaks. These lines can be
traced back from the fuel tank. Check clamps for tightness and
replace as necessary. Smell and look for signs of fuel in the engine
compartment.
To replace a fuel fi lter, ensure that the engine is turned off. ALso
ensure the battery switch is turned off. Eliminate all potential
sources of spark of fl ame from the boat before replacing the fuel
fi lter. Locate the fuel fi lter, typically near the fuel pumps. Using a
fi lter wrench, loosen and remove the fuel fi lter. Be prepared to catch
excess fuel that may spill. Dispose of the used fuel fi lter according
to environmental standards. Lubricate the new fuel fi lter gasket with
clean engine oil. Screw in the fuel fi lter and tighten according to the
engine manufacturer’s specifi cations.
