Typical example
1. Ensure that the fuel tank is full and any fuel valve
(if equipped) is in the "ON" position.
2. If the application has a gravity feed fuel system,
then loosen vent screw (1) and allow fuel to flow.
When fuel free from air comes from the vent
screw, tighten the vent screw (1) by hand . If the
fuel system is not a gravity feed fuel system, then
go to Step 3.

Typical example
3. Loosen the vent screw (2) on the secondary fuel
filter. Turn the keyswitch to the "RUN" position.
4. The keyswitch will allow the electric priming pump
to operate. When fuel free from air comes from the
vent screw (2), tighten the vent screw to a torque
of 24 N·m (212. lb in). Then, operate the electric
priming pump for 2 minutes.
5. Turn the keyswitch to the "OFF" position. The fuel
system will now be primed and the engine should
be able to start.
6. Operate the engine starter and crank the engine.
After the engine has started, operate the engine at
low idle for a minimum of 5 minutes. For constant
speed engines do not apply load for 5 minutes.
Note: Operating the engine for this period will help

ensure that the fuel system is free of air. DO NOT
loosen the high-pressure fuel lines to purge air
from the fuel system. This procedure is not
required.
7. Ensure that the fuel system is free from leaks.
After the engine has stopped, you must wait for 10
minutes to allow the fuel pressure to be purged from
the high-pressure fuel lines before any service or
repair is performed on the engine fuel lines. The 10
minute wait will also allow static charge to dissipate
from the low-pressure fuel system. If necessary,
perform minor adjustments. Repair any leaks from
the low-pressure fuel system and from the cooling,
lubrication, or air systems. Replace any high-
pressure fuel line that has leaked. Refer to
Disassembly and Assembly Manual, "Fuel Injection
Lines - Install".
If you inspect the engine in operation, always use the
proper inspection procedure to avoid a fluid
penetration hazard. Refer to Operation and
Maintenance Manual, "General hazard Information".
If the engine will not start, refer to Troubleshooting,
"Engine Cranks but will not Start".
