Fuel System Circuit

Circuit Description:
The gear pump draws fuel from the fuel tank through the fuel filter and antidrainback valve. The gear pump develops
up to 2206 kPa [320 psi] of fuel pressure. The fuel flows through the fuel filter screen and fuel shutoff valve to the
fueling and timing actuators and the fuel pressure sensor.

Component Location:
The 1724 kPa [250 psi] regulator controls the fuel pressure. All components are located on the fuel delivery housing
on the intake side of the engine.

Shop Talk:
The fuel pressure is monitored by the Electronic Control Module (ECM). If the fuel pressure is outside an acceptable
range, the fault code is activated. The acceptable range of fuel pressure can be viewed as Fuel Pressure Lower Limit
and Fuel Pressure Upper Limit in the INSITE™ electronic service tool monitor screen. The fault will log quickly for
large differences in pressure and slowly for small differences in pressure.

Refer to Troubleshooting Fault Code t05-482.
