Step One: Identify the Leak. Before you can get the air out of the system, you have to know how it got in.
Step Two: Back off the Bleed Screw.
Step Three: Operate the Manual Fuel Pump Primer.
Step Four: Bleed Any Additional Points.

How do I get my diesel to start after I run 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).

What causes airlock in diesel engine?
In general, it’s caused by air being able to leak back into the top end of the fuel system after the engine is switched off. Then the vehicle will only start and run for a few seconds using a small amount of fuel that might still be in the injector pump.
What causes air in fuel line diesel?
When you change a diesel fuel filter, run out of fuel or disturb the fuel system, air is trapped. When you try to start the engine this air acts as a lock, preventing the normal supply of fuel into the cylinder.
What happens if air gets in fuel line?
When unwanted air finds its way into your fuel system, your car becomes at risk of reduced performance, and even engine failure. The best way to prevent this from happening is to take your vehicle in for regular maintenance.
How do I fix an airlock in my gas tank?
Just turn the ignition on, but to start, then back to off. That will turn the fuel pump on for a couple of seconds. The fuel pump should push the air thru the line and back into the tank on most engines.
What should a driver do if the fuel system becomes air locked?
The solution may be as simple as bleeding the fuel system to release the air.
What should a driver do if the fuel system becomes air-locked?
Move the engine stop/run switch to the RUN position.
Allow the fuel pump to run until it stops (about 2 seconds).
Move the engine stop/run switch to the STOP position.
Repeat steps 3–5 four to five times.

How to Prime a Transfer Pump
Bolt the pump on using the attached bolts and gaskets.
Press the fuel pump down a few times to increase the pressure in the transfer pump.
Close the fuel line and remove the pump. The transfer pump is now primed and ready to function on its own.
Do transfer pumps need to be primed?
They need to be primed before they’re ready to operate. When it comes to pumps, priming basically means the pump casing must be filled with liquid before the pump can operate.
How do you prime a transfer pump?
Do you have to prime a fuel transfer pump?
In most cases, you won’t need to prime your fuel pump after installing a new one. Manual (non-electric) fuel pumps in older vehicles may need to be primed to get the flow of fuel started.
Why won’t my car start after I change the fuel pump?
Since the major cause of hard start after fuel pump change is the lack of fuel pressure, the solution to this problem would be to remove the fuel line that connects to the fuel filter. Then, get a fuel pressure gauge installation. Thereafter, plug a hose and get it connected to the line that links to the fuel filter.
There is no suction. The bypass on the transfer pump may be blocked with debris or possibly broken. This can be caused by debris within the fuel & not having a strainer or filter fitted to the pump. If there is a strainer, ensure it’s clear; clean & remove debris as necessary, & inspect the strainer seal.
How do you ground a fuel transfer pump?
How do you run a fuel pump directly to a battery?
To do this, you’ll need to disconnect the wire from the pump and connect it directly to the positive terminal of your battery. Then, run a jumper wire from the negative terminal of your battery to a ground point on your vehicle. This will complete the circuit and allow power to flow directly to the fuel pump.
