Installation And Connection Of The Fuel Pump; Installation And Connection Of The Carburetor - Rotax 125 MAX DD2 Installationsanleitung

Attention: To warrant the best possible engine cooling ensure that the air stream covers the
complete radiator area.

12. Installation and connection of the fuel pump

Attach the fuel pump with the two supplied rubber buffer, locknuts and washer on
the side of the bracket so that the fitting for the fuel supply inlet (3) (arrow on pump
housing) points towards the driving direction.
Cut off two pieces, each 29 cm (11,41 in)
long from the supplied fuel hose and fit
one each on the lower impulse fitting (1)
and fuel outlet connection (2) (arrow on
pump housing).
Remove the cap from the impulse fitting at
the engine housing.
Connect the impulse hose of the fuel
pump with impulse fitting at the engine
housing.
Attention: For proper operation of the fuel pump, keep the impulse line as short as possible but
never longer than 29 cm (11,41 in).
Attention: If oil condensate collects in the impulse hose when the engine is not running, it must
be drained by pulling the impulse hose off the fuel pump. Oil accumulated in the fuel
pump could impair operation of the fuel pump.
Establish connection with fuel hose between the outlet on fuel tank and inlet (3) on
the fuel pump.
Install the supplied fuel filter in a proper position in the fuel line between fuel tank
and fuel pump.
Attention: Route the fuel line from the fuel tank to the fuel pump so that it does not touch any
moving parts or the track and attach the fuel line onto the top side of the chassis
tube.
Attention: The flow in the impulse hose and fuel lines must not be restricted by the use of
cable ties.
Attention: The use of an extra fuel filter must not cause further flow resistance in the fuel line
between the fuel tank and the fuel pump.

13. Installation and connection of the carburetor

Remove the transport plug from the carburetor.
Fit carburetor into carburetor socket and secure with hose clamp in vertical position.
Connect the outlet hose of the fuel pump with fuel inlet on carburetor.
