4L2: Filling the Fuel Tanks
With the large fuel tanks, you can fuel the boat pretty fast using a standard hose and nozzle (like those on auto
gas pumps).
Fill both the tanks completely but do not spill fuel.
4L3: Fuel Fill Pipe Locations
Taking the hose around the cockpit to reach the fill caps on the inside of the bulwarks adjacent to each side of
the saloon midships.
4L4: Fuel Filters
Diesel engines require absolutely clean fuel to operate
continuously. As a result, there are two kinds of fuel filters on
the boat. The primary filters are mounted on the inner side
of each fuel tank and consists of two filters controlled by a
valve allowing one to be selected at a time (only one filter on
the generator). That way, if one is clogged, you can switch to
the other.
The secondary filter is on the engine itself. It is very fine
mesh and is the final protection to be sure
If the engine stops, it is likely a filter is clogged. Follow through
carefully, and remember you will have to prime the engine to
re-start it. See the engine manual for this procedure.
4L5: Fuel Management
In the starboard aft side of the engine room there is a fuel
manifold consisting of a set of valves for the fuel supply to
the main engine and generator, and another set for the fuel
return from these engines back to the ship’s tanks.
In addition, there are visual sight gauges at the forward end of
each tank that let you see the level in each.
Failure to have the same tank supplying and returning
fuel risks spilling fuel as the tank getting the “returned” fuel overflows.
4L6: Fuel Manifold
The Fuel Manifold is located directly on the inner side of the starboard fuel tank aft.
Note that all the valves on the manifold are vertical! This is the normal set and great caution should be
used before they are set any differently.
Each engine has a fuel supply and, since extra fuel is pumped to the engine that is used to cool the engines
injection pump, there is a fuel return line as well. At slow speeds, these return lines are pumping a lot of fuel;
The outer two gauges over the lower helm
show approximate fuel levels.
Primary filters. The valve points to the selected filter.
