6.10 Separate fuel tank
You can also install the fuel tank separately in some designs.
In these cases, install the fuel tank in a dry and well-ventilated
room and as close as possible to the pump set.
6.10.1 Fuel tank installation
The fuel tank outlet must be placed higher than the centerline of
the high-pressure fuel pump at the engine. The two separate
concrete foundations must be in same level h1 = h2.
Placing the pump set (1) and fuel tank (2) at the same level
ensures gravity supported feeding of fuel to the high-pressure
fuel pump at the engine. See fig. 20.
The fuel tank must be fastened to the foundation with the
mounting brackets.
Fig. 20
Example, correct installation of fuel tank
The fuel tank must be fastened to the floor through the mounting
brackets.
If there is no connecting block, connect the fuel pipes as shown in
fig. 21 to the flow pipe (pos. A, from the manual fuel supply pump)
and the return pipe (pos. B, from the injection pump).
Fig. 21
Connecting the fuel pipes without connecting block
If there is a connecting block (see fig. 22, pos. A), connect both
fuel pipes to the connecting block. The connecting block is
marked "SUPPLY" for the incoming pipe and "RETURN" for the
return pipe.

Note
Observe the standards when sizing and installing
a separate fuel tank.
Caution
Make sure that the base of the fuel tank is
installed at the same level as the pump and
engine base frame.
