Bleeding The Fuel System - Scania PDE Operator's Manual

Bleeding the fuel system

1.
Attach a clear plastic hose to the bleed nipple
on the fuel manifold. Place the end of the
plastic hose in a container that holds at least
3 litres (1 US gallons).
2.
Open the bleed nipple and pump with the
hand pump until fuel comes out of the hose.
If the fuel system is empty, it is necessary to
pump approximately 200 strokes in order to
draw up the fuel. Depending on the installa-
tion, a much greater number of pump strokes
may be required before fuel comes out.
3.
Pump until fuel without air bubbles comes
out.
4.
Close the bleed nipple on the fuel manifold
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. The fuel fil-
ter may then need to be tightened further.
