Venting the fuel system using a hand
pump
Use a suitable container. The fuel collected must
be disposed of as specified in national and inter-
national laws and regulations.
1. Attach a clear plastic hose to the bleed nipple
on the fuel manifold (1). Start by wiping off
the bleed nipple. Place the end of the plastic
hose in a container that holds at least 3 litres
(1 US gallon).
2. Open the bleed nipple and pump with the
hand pump (2) until fuel comes out of the
hose. If the fuel system is empty, it is neces-
sary to pump approximately 200 strokes in
order to draw up the fuel. Depending on the
installation, a significantly greater number of
pump strokes may be required before the fuel
comes out.
3. Pump until fuel without air bubbles comes
out, approximately 20 strokes.
4. Close the bleed nipple and remove the plastic
hose.
5. Pump approximately 20 strokes with the
hand pump until the overflow valve opens. A
hissing sound should be heard.
6. Start the engine. The engine should be easy
to start.
7. If the fuel filter has been renewed, check that
no fuel is leaking from the filter. Further
tighten the filter if it is leaking.
