ELECTRIC FUEL PUMP
The pump is housed inside the fuel tank on a special tray which also supports the fuel level gauge and is
fitted with a gauze filter at the pump inlet.
The pump is the volumetric type (G-Rotor) and is designed to run on unleaded fuel.
The rotor is moved by a direct current motor supplied at the battery voltage directly by the appropriate
relay operated by the control unit.
The motor is immersed in the fuel which has a detergent and cooling effect on the blades and the mani­
fold.
The pump is equiped with an excess pressure valve, which short circuits the supply with the inlet if the
pressure in the supply circuit exceeds 5 bar, to prevent the electric motor from overheating.
In addition, a one-way valve on the supply prevents the draining of the entire fuel circuit when the pump
is not working.
The nominal capacity of the pump varies according to theangular speed of the rotor and therefore the
supply voltage: with a voltage of 12 V it is around 140 l/h.

FUEL FILTER
The filter, protected by a shield fixed under
the bodyshell, is inserted along the fuel sup­
ply pipe. It is made up of a steel casing and a
polyurethane internal support which has a
high filtering capacity element.
NOTE There is an arrow on the outer casing
which indicates the direction of the
flow of the fuel and the correct fit­
ting position.
