Double fuel tanks
Double tanks as shown in the figure should be con-
nected at bottom by means of pipelines fitted with
shut-off cocks. The lower connecting pipe should
have an internal diameter of at least " so that the
tanks can be filled from either side of the boat. Other
fuel tank shapes that are adapted to the installation
geometry are of course acceptable. Whatever shape
is chosen, it is important to design the tank to provide
a low part where water and sludge can be drained
NOTE! An extra fuel filter with water separator must
be installed for all Volvo Penta engines.
If a day tank is installed, then it is advisable to con-
nect the return line to this tank.
A shut-off valve must be installed in the supply pipe,
between the tank and the filter. This tap should be
able to be shut from a location outside the engine
room.
