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 forward engine room bulkhead and consists of two filters
controlled by a valve allowing one to be selected at a time. That way, if one
is clogged, you can switch to the other. The secondary filter is on the engine
itself. It is very fine and is the final protection to be sure the engine’s fuel is
absolutely clean.
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 Manifolds
The Fuel Manifold is located at the forward end of the engine
room. 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; you
must be careful not to set the valves so that a return line is
switched to a tank for long that is not also supplying fuel,
lest it overflow and pollute the water through the tank vents’
overflowing!
