XG 350 V6-3.5L (2002)
Standard value : 320 - 340 kPa (3.26 - 3.47 kg/sq.cm, 46 - 49 psi)
8. Measure the fuel pressure when the vacuum hose is connected to the pressure regulator.
Standard value : Approx. 255 kPa (2.57 kg/sq.cm, 37 psi)
9. If the results of the measurements made in steps (7) and (8) are not within the standard value, use the table to determine the probable cause, and
make the necessary repairs.
10. Stop the engine and check for a change in the fuel pressure gauge reading, which should hold for approximately 5 minutes. If the gauge indication
drops, observe the rate at which it drops. Determine and remove the causes according to the table.
11. Reduce the pressure in the fuel line.
12. Disconnect the hose and the gauge.
CAUTION: Cover the hose connection with a shop towel to prevent splashing of fuel caused by fuel residual pressure In the fuel line.
13. Replace the O-ring at the end of the hose.
14. Connect the fuel hose to the delivery pipe and tighten to the specified torque.
15. Check for fuel leakage.
-
Apply battery voltage to the fuel pump drive terminal to operate the fuel pump.
-
With pressure, check the fuel line for leaks.
