Typical example
2.
Remove the protection cap (1). Depress valve (2)
in order to purge air. Perkins recommend that a
tire inflator with a suitable length of clear hose
attached to be used. Refer to illustration 56 .

3.
With tool (B) installed to valve (2) turn the
keyswitch to the ON position. When fuel has filled
the bowl at the bottom of the filter (3), the tool (B)
can be removed. Ensure that the protection cap (1)
is install.
4.
After the keyswitch is turned to the ON position, the
relay (4) will allow operation of the electric priming
pump for 2 minutes. After 2 minutes, turn the
keyswitch in order to operate the starter and crank
the engine. If the engine does not start, turn the
keyswitch OFF and then ON again and allow 1
minutes 30 seconds before starting the engine.
5.
After the engine has started, operate the engine at
a low idle for a minimum of 5 minutes. Operating
the engine at a low idle will help ensure that the air
has been removed from the fuel system.
After the engine has stopped, you must wait for 10
minutes in order 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.
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, “Fuel Injection Lines -
Install”.
If you inspect the engine in operation, always use the
proper inspection procedure in order to avoid a fluid
penetration hazard . Refer to Operation and
Maintenance Manual, “General hazard Information”.
NOTICE
The low-pressure fuel system can be pressurized for
a time period after the engine has stopped operating.
The operating pressure of the low-pressure fuel sys-
tem can be 500 kPa (73 psi). The secondary fuel fil-
ters should be drained before any maintenance of the
low-pressure fuel system is carried out.
If the engine will not start, refer to Troubleshooting,
“Engine Cranks but will not Start”.
