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 are not 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 escap-
ing fuel, see a doctor at once. Serious infection or reaction can develop if proper medical treatment is not
administered immediately.

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 bolt “A” (
Figure 10
) on top of the
filter. Pump hand primer “B” on fuel lift pump until
pure fuel (no bubbles) escapes from bleed bolt “A”.
Tighten bleed screw “A”.
3. Loosen bleed screw “C”. Pump hand primer “B”
until pure fuel (no bubbles) escapes. Then tighten
bleed screw “C”.
4. If the engine does not start after the above bleed-
ing process, loosen a fuel line at the injector while
cranking the engine with the starter motor until pure
fuel escapes. Then tighten the connection. Do each
line one-at-a-time.
5. After the engine has started, use a piece of cardboard
to look for fuel leaks.
