the fuel line and connecting it to the specific hose 268496 (routed to an external canister),
and by activating the fuel pumps with the specific harness 264468, and an external battery.
Both parts are provided with the maintenance kit.

same location.
Disconnect the quick

fuel line and connect
to the specific hose.
Disconnect the pumps electrical
connector and connect to the
specific harness.
