Troubleshooting Test Steps Values Results
2. Check Fuel Pressure Sensor "A"
A. Record the unfiltered fuel pressure from Cat ET. Record the value in Table 6.
B. Remove fuel pressure sensor "A" (2).
C. Install a 5P-1318 Adapter into the port of the pressure sensor "A" (2).
D. Install the 123-0783 Fluid Sampling Valve Gp onto the 5P-1318 Adapter.
E. Install a 8T-0855 Pressure Gauge onto a 6V-3990 Coupler.
F. Install the 6V-3990 Coupler onto the 123-0783 Fluid Sampling Valve Gp.
G. Record the fuel pressure from the pressure gauge. Record the pressure in Table 6.
Pressure Sensor
Result: The gauge value of the fuel pressure is within 69 kPa (10 psi) of the unfiltered fuel pressure reading shown in Cat ET.
Proceed to Test Step 3.
Result: The gauge value of the fuel pressure is not within 69 kPa (10 psi) of the unfiltered fuel pressure reading shown in Cat ET.
Repair: Replace the pressure sensor. Verify that the problem has been resolved.
If the problem is not resolved, proceed to Test Step 3.

3. Inspect the Fuel Supply and Return Lines
A. Visually inspect the fuel lines between the primary filter base and the inlet to the fuel injection pump. Also, inspect the fuel cooler, if equipped. Inspect the fuel return line from the head to the fuel tank. Inspect the lines for restrictions, pinching, and swelling. Refer to Systems Operation/Testing and Adjusting, "Fuel System - Inspect" for additional information.
Inspect Lines
Result: The fuel lines and the cooler (if equipped) are OK.
Proceed to Test Step 4.
Result: The fuel lines and the cooler (if equipped) are not OK.
Repair: Make the necessary repairs. Verify that the problem has been resolved.
If the problem is not resolved, proceed to Test Step 4.

4. Replace the Return Fuel Pressure Regulator
A. Replace the fuel pressure regulator.
Pressure Regulator
Result: The regulator was replaced. Verify that the problem is resolved.
If the problem is not resolved, proceed to Test Step 5.

5. Inspect the Relief Valve for the Fuel Transfer Pump
A. Inspect the relief valve for the transfer pump. The spring must move freely.
Transfer Pump
Result: The relief valve is stuck CLOSED.
Repair: Replace the fuel transfer pump. Verify that the problem has been resolved.
Result: The relief valve is OK.
Repair: Clean the relief valve and reinstall the relief valve. Verify that the problem has been resolved.
