(1) Vent plug
(2) Fuel filter base
Loosen the vent plug (1) on top of fuel filter base (2).
Illustration 2 g00310703
(3) Fuel transfer pump
Operate the priming lever on the bottom of the fuel transfer pump (3) until fuel, which is free of air, flows from the vent plug. Tighten the vent plug. Note: If the drive cam of the fuel transfer pump is at maximum lift, the priming lever cannot be operated. The crankshaft must be rotated one revolution.

(4) Nut for the fuel line to the air inlet heater
If the fuel line for the air inlet heater has been drained, loosen the nut (4) for the fuel line at the air inlet heater. Operate the priming lever on the bottom of the fuel transfer pump (3) until fuel, which is free of air, flows from the fuel line. Tighten the nut for the fuel line to the air inlet heater to a torque of 22 N m (16 lb ft).

(5) Nuts for the fuel line to the fuel injection nozzles
Air from the fuel lines is also removed by loosening the nuts (5) for the fuel line at the fuel injection nozzles. Operate the starting motor until the fuel, which is free of air, flows from the fuel line. Tighten the nuts for the fuel lines (5) to a torque of 22 N m (16 lb ft).
Do not crank the engine for more than 30 seconds. Allow the starting motor to cool for two minutes before cranking again.Turbocharger (if equipped) damage can result, if the engine rpm is not kept low until the engine oil light/gauge verifies the oil pressure is sufficient.
Remove Air From The Fuel System On Type 2 Engines and 7BJ Engines
Note: For a complete description of Type 1 and Type 2 engines, refer to the Systems Operation, Testing and Adjusting Module, "Engine Design" for more information.If air enters the fuel system, the air must be purged before the engine can be started. Air can enter the system when the following events occur:
The fuel tank is empty or the tank has been partially drained.
The low pressure fuel lines are disconnected.
A leak exists in the low pressure fuel system.
The fuel filter is replaced.Use the following procedure in order to remove air from the fuel system:

(3) Fuel transfer pump
Loosen the vent plug (1) on top of the fuel filter and filter bases. Operate the priming lever on the bottom of the fuel transfer pump (3) until fuel, which is free of air, flows from the vent plug. Tighten the vent plug.

Fuel filter and filter assemblies (Stanadyne Fuel System)
(1) Vent plug for the fuel filter (if equipped)
Stanadyne fuel system Loosen vent plug (1) on top of primary fuel filter. Operate the priming lever on the bottom of the fuel transfer pump (3) until fuel, which is free of air, flows from the vent plug. Tighten the vent plug.Loosen vent plug (1) on top of the secondary fuel filter. Operate the priming lever on the bottom of the fuel transfer pump (3) until fuel, which is free of air, flows from the vent plug. Tighten the vent plug.Note: If the drive cam of the fuel transfer pump is in the position of maximum cam lift, the priming lever will not operate. The crankshaft must be rotated one revolution.

(4) Nut for the fuel line to the air inlet heater
If the fuel line for the air inlet heater has been drained, loosen the fuel line nut (4) at the air inlet heater. Operate the priming lever on the bottom of the fuel transfer pump (3) until fuel, which is free of air, flows from the fuel line. Tighten the fuel line nut (4) to a torque of 22 N m (16 lb ft).
