Do you need to bleed diesel injectors?
Most secondary fuel filters are equipped with a bleed screw. Then you must bleed the high-pressure fuel system, which is done by loosening the union nuts between the top of the fuel injectors and the fuel line; it just takes a turn or two. Once loosened, use the starter to crank the engine for 10 seconds.

Where is the bleed screw in the fuel line?
The fuel system’s secondary or on-engine fuel filter is located between the lift pump and the high-pressure injection pump, and it’s here that air often becomes trapped. Most secondary fuel filters are equipped with a bleed screw.
How do you Bleed a secondary fuel filter?
Most secondary fuel filters are equipped with a bleed screw. Opening this and working the lift-pump lever until a clear stream of fuel flows out means that you’ve successfully bled the system up to that point. Next comes the injection pump. Most are equipped with bleed screws, and thus the procedure is the same.
How do you fix a bleed plug in a fuel pump?
Most all equipment has a hand priming pump lever to pump fuel through the system and replace trapped air. (Check operator’s manual.) Pump several times until full flow, without air bubbles, escapes from the bleed plug holes. 8. You may need to bleed filters, fuel pump and lines to the injectors.
