1.3. Fuel system
The fuel tank with a capacity of approx. 156 l is located underneath the bed in the starboard aft
cabin. It can be filled through the filler neck marked “Fuel” or “Diesel” located in the starboard aft
side deck. To do so, unscrew the lid. Check whether the ventilation openings are free.
The level can be checked at the main control panel.
The fuel reaches the engine via a suction pipe and a preliminary fuel filter with a water separator.
Due to the short lines, the system consists of fire-resistant fuel hoses.
Please note that the return lines are always open to ensure the return to the tank.

The boat should be refuelled carefully so that no fuel spills onto the deck or into the water. Keep
an oil absorbing cloth at hand. Open the cap and insert the funnel or the fuel nozzle. Take care to
establish contact with the filler neck (earthing). Then start refuelling.
Refuel only from the engine manufacturer recommended kind of
fuel (diesel)!
Only refuel clean fuel. Check and cleanse the filter and the water
separator regularly.
The skipper is responsible that no fuel comes into the water. This can only be prevented if the
fuel gauge is constantly monitored by a second person during the refueling process. In addition
the refueling should be stopped early enough, to prevent the fuel from entering the fuel vent line.
When filling the fuel tank, be aware that at least 5% of the volume should remain free, in order to
prevent leakage from the tank ventilation line
Keep the tank vent thru hull in sight when filling the tank, because fuel could spill out of this area
Due to differences in fuel quality, fuel can become foamy while filling. For this reason, always use
care and slowly fill the fuel tank.
Environmental Protection:
Under no circumstances overfill fuel!
