Section 3
Fuel System
• If E-10 gasoline absorbs enough moisture, it can
suffer phase separation. The ethanol and water
mixture will fall out of suspension and collect in
the lowest parts of the fuel system. The ethanol
and water mixture can damage engines, clog fuel
filters, and corrode metal fuel system parts. Fuel
tanks with E-10 gasoline should always be kept
as full as possible to reduce exposure to moisture
from condensation and humidity.
• Concentrations of ethanol greater than 10% can
change the physical properties of some rubber
and plastic fuel system parts such as gaskets,
hoses, tanks, and filters. Regularly inspect all
non-metal fuel system parts for signs of swelling
or deterioration. In some extreme cases, rubber
parts such as hoses and gaskets can actually
sweat liquid fuel. Be alert for the odor of fuel or
small droplets of fuel near these parts. Always
have fuel system repairs performed by a qualified
marine technician.
