ToggleHow do you bleed air out of the fuel system on a 6.4 Powerstroke?
How do you start a diesel engine after changing the fuel filter?
In some diesel engines, priming the fuel pump can be as simple as turning the ignition key to “run” for several seconds, turning off, and then repeating up to four times. This restart procedure will most likely be recommended by your manufacturer and allow you to restart the engine after a few minutes.

How do you start a 6.4 Powerstroke after running out of fuel?
Prime the fuel system by turning the ignition on (Run position) for 30 seconds, but do not start the engine. This allows the pump to prime the system. Turn the ignition off, and then crank it for 15 seconds. If it does not start, repeat the first task and this one until it starts (cycle the key).
How do you purge air from a fuel system?
To purge air from the low-pressure side of the fuel system, open fuel-line unions and bleed ports downstream of the pump, one at a time, beginning with those closest to the pump, and continue pumping until fuel, and not air, runs out.
How do you bleed air from a diesel fuel line?
How do you get an airlock out of a diesel engine?
Your fuel lift pump will be mounted on the engine and connected to the primary fuel filter. Begin pumping the lever or plunger while keeping an eye on the bleed screw. You will see bubbles form as air leaves the system. Use your rags or other absorbent material to sop up the fuel as it bleeds out.
What are the symptoms of having air in the fuel line?
Air bubbles in a fuel line can lead to stalling, hiccuping or refusal to start. Keep your fuel lines free of air to help keep your car running smoothly.
What causes air in fuel line diesel?
All diesel fuel has some level of entrained air caused by the natural splashing that occurs in the fuel tank during normal vehicle or equipment operation. Vapor bubbles develop in the Fuel Pro because the pressure inside the Fuel Pro is lower than the atmospheric pressure in the fuel tank.
What happens if air gets in to diesel engine?
The Diesel Fuel System
When air or vapor is forced into the injectors, the lack of diesel fuel also means the lubrication needed to maintain healthy fuel injectors is missing. This results in metal on metal contact which shortens the functional life of your injectors.
How do I know if my fuel return line is clogged?
- Strong fuel odor, engine misfires, and decreasing power.
- Carburetor flooding, engine stalling, and hard starting.
- Fuel leaks.
How do you check air in fuel system?
To check if there is air in the fuel line, open the filler cap and turn on your engine. Let it run for a few minutes then turn it off and open the cap back up. If the engine is still running after a few minutes, it means there air is getting into the tank and likely in your fuel lines.
Why is it necessary to bleed a diesel system?
Bleeding the low pressure side prevents, among other things, defects to the high pressure pump which can occur during filter change without manual bleeding, for example. Diesel fuel provides the sole lubrication within the system. That is why it is particularly important that it never runs dry.
How do you diagnose a fuel system problem?
A fuel system should be carefully tested for pressure, volume, and electrical integrity before condemning the fuel pump. Often the first step in diagnosing a faulty fuel system is to simply listen. Turn the ignition key to the run position and carefully listen for a slight humming sound coming from the fuel tank.
