Figure 541 ZTSE4692
The fuel tes t fitting is used to measure fuel inlet
restriction or fuel pressure.
When measuring fuel inlet restriction, the fitting is
installed at the diagnostic port (inlet-side) of the fuel
filter hous ing.
When measuring fuel pressure, the fitting can be
installed on the fuel rail instead of the Shrader valve .
The Fuel/Oil Pressure Test Coupler can then be
connected to the fuel test fittingtomeasurefuel
pressure or fuel inlet restriction.
ICP System Test Adapter
Figure 542 ZTSE4594
The Injection Control Pressure (ICP) System Test
Adapter was first used to pressurize the ICP system
for the International® VT 365 diesel engine to test
ICP system integrity with the influence of the Injection
Pressure Regulator (IPR) valve. This adapter is used
to take an oil sample or measure oil pressure at the
Engine Oil Temperature (EOT) sensor port for the
International® DT 466, DT 570, and HT 570 diesel
engine.
