It is not necessary to loosen or disconnect the connections and pipings in order to bleed the fuel system.
Pump the fuel, acting on the hand pump handle (1) until you notice a strong resistance generated by system pressure raise.
Activate engine start, but do not press the accelerator. If engine does not start within 20 seconds, interrupt the start actuation and wait at least one minute before trying again. If the engine does not start, repeat the bleeding operation.
