SP10. BLEEDING THE FUEL SYSTEM
CAUTION: Escaping diesel fuel under pressure
can penetrate skin causing serious personal
injury. Before disconnecting lines be sure to
relieve all pressure. Before applying pressure,
be sure all connections are tight and lines,
pipes and hoses aren't damaged. Fuel escaping
from a very small hole can be almost invisible.
Use a piece of cardboard or wood, rather than
hands, to search for suspected leaks. If injured
by escaping fuel, see a doctor at once. Serious
infection or reaction can develop if proper medi-
cal treatment isn't administered immediately.
1. The fuel system is self-bleeding. However, any
system may need manual bleeding when:
a. A new fuel fi lter is installed;
b. The engine has run out of fuel;
c. The fuel lines, injection pump or any other fuel
system component has been removed and installed.
2. Loosen bleed screw “A” (
Figure 11
) on top of the
fi lter. Pump hand primer “B” on fuel lift pump until
pure fuel (no bubbles) escapes from bleed screw
“A”. Tighten bleed screw “A”.
3. Loosen bleed screw “C”. Pump hand primer “B” on
fuel lift pump until pure fuel (no bubbles) escapes
from bleed screw “A”.
4. If the engine does not start after the above bleeding
process, loosen a fuel line at the injector. Crank the
engine until fuel escapes, then tighten the connec-
tion. Do each line
one at a time.
5. After the engine has started, check for fuel leaks.
