TYPICAL FUEL TANK FILL/VENT
Fuel tank fi ll fi ttings
a r e n o r m a l l y
located on the deck.
They are marked
diesel. Never pump
gasoline in a fuel
tank designated for
diesel fuel. After
fueling close the fi tting tightly. Failure to secure the fuel
fi tting tightly may allow water to enter the fuel tank and
eventually the engine fuel system. Periodically lubricate
the fuel fi tting O-ring by coating with clean diesel fuel.
Th is will help keep the O-ring pliable and retain its
sealing properties.
Th
e fuel vent serves as a pressure relief for the diesel
tank and is a safety overfl ow device. Th e vent is found
below the fuel fi ll fi tting at the starboard hull side. It has
a screen inside which needs to be periodically cleaned.
Insects can cause the vent to clog resulting in increased
pressure in the fuel system especially noticeable when
fi lling the fuel tank. In extreme clogging cases the fuel
will emerge from the fi ll because the vent is not able to
relieve the air in the fuel tank that is being replaced with
diesel fuel.
Placed at the top of the fuel tank is an electronic fuel
sender. This device reads the amount of fuel remain-
ing in the fuel tank and sends a signal to various dis-
plays including the fuel system display on the Garmin
chart plotter(s)..
Always use the one-third rule with diesel fuel. One-third
for outbound cruising, one-third for inbound cruising,
and the remaining one-third fuel supply for reserve.
Note the green ground terminal and the fuel tank label.
Check the ground terminal at least twice yearly for
tightness since a loose connection could result in erratic
or no fuel reading.
