Suction tool
for fuel system
NOTE !
Nanni recommends bleeding the fuel system using
suction tools rather than with a hand pump. This is a
quicker and simpler method, which ensures a complete
bleeding.
1. Open the bleed niple on the high pressure pump (3)
and connect the suction tool to it.
2. Hold the suction tool straight and draw out at least a
full container of fuel.
3. Once the fuel coming out of the hose is free of air
bubbles, then bleeding is complete.
4. Close the ventilating valve on the high pressure
pump. Remove the hose and suction tool.
5. Start the engine and check that no leaks.
BLEEDING THE FUEL SYSTEM USING A HAND PUMP
ON 16 LITRES MARINE ENGINE XPI
ENVIRONMENT
Use a suitable container. The fuel collected must be dis-
posed of as specified in national and international laws
and regulations.
1. Turn the rotary control so that it is pointing towards
filter B. The fuel will then flow through the filter:
2. Unscrew the hand pump handle (1) and connect a
transparent plastic hose to the bleed nipple on the fuel
filter (2). Let the plastic hose drop into a container that
holds at least 5 litres (1.3 US gallons).
3. Open the bleed nipple on the fuel filter.
4. Pump with the hand pump until fuel without bubbles
comes out.
