B.6.3.1.C
In case of the use of two tanks it is essential to install a dual flow valve, which
can act on both the delivery branch and on the return to the tank. A valve
with these characte ristics is available as an accessory with the cod. C107.
In case a safety valve is installed on the return to the fuel tank it is important
to install a non-return valve, as close as possible to the tank: this valve is to
prevent the fuel contained in the tanks from flowing to the engine or into the
cabin in the event of rollover or serious damage to 'fuel system.
