As is shown in the figure, fuel coming from a tank
K fitting is taken in by suction by the pump G via
a hose H and then fed to the joint C via the hose
F.
The amount of fuel necessary for generating set
operation will be fed through the hose J to the
generator unit A; while any excess fuel will return
to the tank via the return fitting E.
Inside the joint C, a flow rate reducer B should be
installed consisting in a fit-in cylinder with a 2.5
mm ID. Each pipe coupling must be secured with
a special clamp.
On the generating set front is a three-pole
connector (Fig.13 Ref.8). Checking the wiring
diagram, identify the two auxiliary fuel pump
control poles (+12 and GND ). Two cables with
minimum cross sections of 1 sq.mm must be
connected to those two Faston terminals with
special connectors to reach the auxiliary pump
poles. (Fig.15 Ref. G)
4.9 (Optional) tank installation instructions
The fuel tank installation position (Fig. 10) must
be chosen so as to ensure that the fuel hose
length is reduced to a minimum.
Also ensure that the hose cross-section is not
reduced due to choking, bending or crushing. We
advise the install the tank at the same height as
Dealers can supply two different fuel tank models
to meet any installation requirements.
• For standard vehicle installation, use the
optional tank code 05472 (Fig.16 Ref.8) with a
capacity of 15 litres; the filler (Fig.16 Ref.5) is
supplied complete with a closing plug. (Fig.16
Ref. 6)

Should it not be possible to observe the
maximum
requirements, an electric fuel pump can be
installed (available as an optional part, code
00507) which can easily overcome over 1 metre
level differences between the fuel tank and the
generating set.

The fuel cut-off tap (Fig. 18 Ref. 3) can also be
screwed onto two different threaded pipe fittings
(Fig.18 Ref. 4) according to different installation
positions.
