started. Air can enter the fuel system when the
following events occur:

•
The low pressure fuel lines are disconnected.
• A leak exists in the low pressure fuel system.
•
The fuel filter has been replaced.
Use the following procedures in order to remove air
from the fuel system.
Note: Do not bleed the fuel system from the water
separator (if equipped).
1. Ensure that the fuel system is in working order.
Check that the fuel supply from the fuel day tank
