4L2: Filling the Fuel Tanks
With the four fuel tanks in use, you need to fuel the boat carefully using standard hose and nozzle (like those on auto gas
pumps).
Hint: Splashing water on the decks in the area of each fuel fill (before opening the caps!), then placing an oil-absorbent
pad with a hole in it for the filler before filling will help keep any spilled fuel from staining the decks!
Fill all the tanks completely but do not spill fuel!
Do not fill the lazarette tanks!
4L3: Fuel Fill Pipe Locations
Fuel fills for the two forward and aft engine room tanks are on the side decks (two per side),
while the other two fuel fills for the lazarette tanks are in the cockpit. Take the hose around
the boat as necessary to fill all the tanks.
4L4: Fuel Filters
The primary fuel filters get larger impurities out of the fuel before it reaches the engine’s
fuel pump. There are a pair of these primary filters for each main engine The filter in use
from each pair is selected by a valve (arrow) on the front of each filter unit.
There is another filter in the engine room for the generator just inboard of that unit.
The secondary fuel filter is on the engine itself just before the injection pump system. It is a
very fine filter, and is the final protection to be sure the engine’s fuel is absolutely clean.
If an engine stops, it is likely a filter is clogged (unless, of course, you’ve run out of fuel!)
Follow engine manual instructions carefully, and remember you may have to prime the
engine to re-start it. See the engine manual for this procedure.
You can see the mid and
forward tank fills on this
sidedeck.
Main engine primary fuel filters are in the engine
room, starboard forward corner. Arrow points to valve.
