4.1.3 Fuel tank
A 86 l stainless steel diesel tank is
installed under the forward port
bunk in the saloon. It is filled
through the screw cap on the main
deck towards the front port side of
the cabin roof structure (marked
FUEL with symbol).
Supply of and return to the inboard
diesel engine occurs through a
fixed copper pipe with fireproof
fuel hoses at the ends in accordance
with ISO 7840. Out-board
ventilation of the fuel tank is
carried out via a swan neck in the
locker to the port deck and exits at
the port side edge of the deck.

4.1.4 Fuel supply/circulation
The feed pipe goes from the inlet pipe on the fuel tank, via a quick shut off valve on the fuel
pipe to the coarse filter/water separator under the bunk in the stern cabin and on to the fine
filter and diesel pump. The engine return pipe to the tank is situated almost parallel. A quick
shut off valve is installed on the feed pipe. This is reached by lifting up the forward padded
seat port side in the saloon.
IMPORTANT
Perfect running of the engine is only possible with clean
fuel. Therefore it is absolutely essential to regularly
inspect and clean the filter and water separator.
Warning
Turn off the engine, heating and the cooker when filling the tank.
Never smoke while filling the tank!
Never approach with a naked flame!
