TRUCK SERVICE MANUAL
FUEL SYSTEM
Kit, Part No. AR-05592, enables valve to operate against
the higher fuel pressure plus the spring load.
The orifice disc, with the center hole, restricts the fuel
pressure loading on the spring loaded disc.
This allows
the spring loaded disc to operate like the standard disc
without the fuel pressure effect.
The high pressure valve will be valuable In applications
having shut-down controls where immediate starts are
required after a control has broken the electrical circuit.
The engine may be started with this kit as soon as the
operator desires.
Arrangement of AR-05592 kit in the shut-off valve is
shown in Fig. 5-44.
