1 FUEL
TANK
Fuel tanks should be made of appropriate material such as
(stainless) steel or plastic. Steel tanks should not be
galvanised or painted inside. Condensation can occur in
metal tanks when temperature changes. Therefore, water
accumulates at the bottom of the tank and provisions
should be made for the drainage of this water.
The tank will need a filling connection, a return connection
and an air ventilation connection which will require
protection against water entry.
Some official regulations do not allow connection points at
the base of the fuel tank; in this instance connections are
to be made at the top of the tank with internal tubing down
to a few cm above the bottom of the tank.

FUEL LIFT PUMP
The generating set itself is equipped with a fuel lift pump;
therefore the tank can be installed at a lower level than the
generating set. The maximum suction height is 1 m.
If the pump has to lift the fuel higher than one meter an
external fuel lift pump must be installed. The control board
is already prepared to connect an extra fuel pump.

FUEL PIPES
When the tank is above the generating set (figure 3)`we
recommend ending the return line on the top of the tank .
When the return is on the top - in case of a leakage the
return line cannot overflow because of siphoning. One will
only need a fuel cock in the fuel supply line.
When the tank is below the generating set (figure 4) we
recommend ending the return line on the bottom of the
tank (A) below the inlet of the supply line to discharge
under the lowest fuel level. This prevents air getting into
the fuel line. Here also one needs a fuel cock only in the
supply line
Both supply and return fuel pipe lines should be
appropriate material and 8 mm outer diameter tubing. The
quality of the tubing of fuel pipes could be submitted to
local regulations depending on the application of the
vessel.
The fuel pipes can be plumbed to the flexible hoses which
are on the generating set and have a connection to fit to 8
mm pipe. This fuel lines fulfils CE standards and are
according to ISO 7840 A2. It is important to avoid bends in
the pipes, as they could trap air bubbles. The return pipe
should never be connected to the suction pipe. Other
consumers of diesel fuel, such as the propulsion engine
and heaters, have to be connected to separate suction
and return pipes.

FUEL FILTERS
A fine fuel filter is installed which requires maintenance.
Whisper Power advises to install an extra fuel filter/ water
fuel separator near the fuel tank.
Before starting your generating set for the first time follow
the fuel system bleeding procedure in the user manual.
