    7. Notice: Correct torque on the high pressure lines is critical. Incorrect torques could result in leaks or lack of power due to restricted fuel flow.‪
  7. To bleed the fuel system, make sure that all high-pressure lines have been tightened to 25 N·m (18 lb·ft) and all banjo bolts to 40 N·m (30 lb·ft).
  8. If equipped with a hand pump on the fuel/water separator, work the hand pump 50 times.
  9. Crank the engine for 30 seconds at a time, but no longer. Before cranking the engine again, wait at least two minutes. The engine should start within four 30-second attempts.
