SP-10. 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 medical treatment isn't administered
immediately.
Figure 10: Fuel System
1. The fuel system is self-bleeding. However, any
system may need manual bleeding when:
a. A new fuel filter 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 nipple (
Figure 10-I
) on top of the fuel
filter. Pump hand primer (
Figure 10-H
) on fuel lift
pump until pure fuel (no bubbles) escapes from the
bleed nipple (
Figure 10-I
). Tighten bleed nipple.
3. If the engine does not start after this bleeding pro-
cess, loosen a fuel line at the injector (
Figure
10-F
) while cranking the engine with the starter
motor until pure fuel escapes. Then tighten the con-
nection. Do each line one-at-a-time .
4. After the engine has started, use a piece of
cardboard to look for fuel leaks.
