Engine installation: Fuel system
Install the fuel system
components
as seen in the picture.
Fuel valve
The main fuel valve is of black color and must be connected to the “fuel valve”
ecu socket in any orientation, polarity will always be correct. Respect the
direction of flow as marked in the valve body.
Fuel filter
The fuel filter must be installed close to the input port on the pump to prevent
any particle to enter in the pump and to damage it. Use a suitable length of
the4 mm clear tubing supplied and keep the tubing on the suction side as
short as possible. Direction of flow inside the filter is not important, but should
be always the same after first use. Do not run the engine without the fuel filter.
Finally connect the fuel pump, the valves and the battery to the ecu as shown.
It is strongly recommended that, after a new installation or modification on the
fuel system, to disconnect the fuel hose from the engine, routing it to a
appropriate container, and run the pump few seconds using the “pump test
function” on the ecu so that some fuel clean all the possible dirt particles that
could have entered in the system.
The starting fuel valve is of gold color and must be connected to the “Gas
valve” ecu socket in any orientation, polarity will always be correct. Respect
the direction of flow as marked in the valve body.
