If your Massey Ferguson 245 tractor won't start after running out of fuel, you may need to bleed the air out of the fuel lines. This is a common issue with diesel engines and can usually be resolved by removing the air from the injection lines. When air is in the lines, fuel cannot form enough pressure to open the injectors, causing the engine to stall. To fix this, you will need to fill the fuel filter and follow the fuel line to locate the small primer pump or the injector lines. Once located, loosen the lines and apply full throttle, ensuring the stop is pushed in so the machine will run.

What You'll Learn
Identify the injection lines
To identify the injection lines on a Massey Ferguson 245, you must first remove the cover in front of the injection pump. This will expose three gear-to-hub bolts, which you should then proceed to remove. After these are out, shut off the fuel and remove the lines as needed, along with the throttle and stop linkage.
At this stage, it is important to check the pump scribe line and make a note of whether it aligns with the line on the case. This is done to ensure that the pump is positioned correctly before proceeding with the next steps. Once this is done, you can move on to removing the pump itself.
The pump is held in place by three stud nuts attached to the case. By removing these nuts, you will be able to take out the pump. It is worth noting that this particular pump has a unique design feature that prevents it from being reassembled incorrectly. Specifically, the drive gear is notched, and the drive hub has a pin that fits into this notch, ensuring proper alignment during reassembly.
Identifying the injection lines on a Massey Ferguson 245 involves carefully following these steps to access and remove the injection pump. This process allows for the inspection and identification of the injection lines connected to the pump.

Remove air from the injection lines
To remove air from the injection lines of a Massey Ferguson 245, start by filling the fuel filter. Then, follow the fuel line from the filter and check if it goes to a small primer pump, which is optional on most machines. If there is no small primer pump, move on to the injector lines at the injector. Loosen all the lines and apply full throttle, ensuring the stop is pushed in so the machine will run. Operate the hand pump about 10 times. Loosen the large nuts at the top of the fuel pipes on the injectors by just half a turn. Turn the engine over again and watch for fuel coming out of the pipe connections at the injectors. When the fuel appears, tighten the connections, recrank the engine, and you should be good to go.

Loosen the large nuts at the top of the fuel pipes
To loosen the large nuts at the top of the fuel pipes on your Massey Ferguson 245, start by locating the fuel pipes on the injectors. Using the appropriate tool, loosen the large nuts by turning them counterclockwise, but only loosen them by half a turn. Do not overtighten the nuts as this can cause damage.
Once the nuts are loosened, turn the engine over and watch the pipe connections at the injectors. You should see fuel coming out of the connections. When you see fuel appearing, tighten the nuts and recrank the engine. This process will help to ensure that any air in the fuel lines is released, and the engine should now be ready to run.
It is important to note that you should only loosen the nuts by half a turn, as mentioned. This is to prevent any fuel leaks and to ensure that the connections are still secure. Over-loosening the nuts can lead to leaks and potential safety hazards.
Additionally, make sure to have a fuel catch pan or container ready to collect any fuel that may drip from the connections when loosening the nuts. This will help to prevent any fuel spills and allow for a cleaner and safer process.

Turn the engine over and check for fuel leaks
To turn the engine over and check for fuel leaks, first remove air from the injection lines. When there is air in the lines, the fuel cannot form enough pressure to open the injectors, as the air compresses instead of remaining solid. Fill the fuel filter and follow the fuel line from the filter to see if it goes to a small primer pump. If your machine does not have a primer pump, go to the injector lines at the injector. Loosen all the lines and apply full throttle, making sure the stop is pushed in so the machine will run.
Loosen the large nuts at the top of the fuel pipes on the injectors by half a turn only. Turn the engine over again and watch closely for fuel coming out of the pipe connections at the injectors. When the fuel appears, tighten the connections, then recrank the engine.
If you are still experiencing fuel leaks, ensure that you have loosened all fuel lines at the injectors to guarantee that all air is out of the lines. Crank the engine and check for a fuel stream from each injector. When you see the fuel stream, tighten the connections and start the engine.

Tighten the nuts and re-crank the engine
Once you have loosened the large nuts at the top of the fuel pipes on the injectors, you can turn the engine over again and watch for fuel to come out of the pipe connections. When the fuel appears, tighten the nuts and re-crank the engine.
To do this, first make sure you have loosened the nuts only by half a turn. You can then turn the engine over and watch the injectors. As soon as you see the fuel start to come out, you can tighten the nuts again. After this, you can re-crank the engine and your Massey Ferguson 245 should be up and running.
It is important to ensure that all the air is out of the lines. This is why you must watch for the fuel to come out of the pipe connections and tighten the nuts as soon as you see the fuel. If there is still air in the lines, the fuel cannot form enough pressure to open the injectors, and the engine will not start.
Therefore, to tighten the nuts and re-crank the engine, you must first loosen the nuts and turn the engine over. Watch for the fuel to come out of the connections, and as soon as it does, tighten the nuts and re-crank the engine.

Frequently asked questions
You need to bleed the air out of the injection lines. First, fill the fuel filter. Second, follow the fuel line from the filter and check if it goes to a small primer pump. If not, go to the injector lines at the injector. Loosen all the lines and apply full throttle, making sure the stop is pushed in so the machine will run.
Remove and fill the filter. Operate the hand pump about 10 times. Loosen the large nuts at the top of the fuel pipes on the injectors by half a turn. Turn the engine over again and watch for fuel coming out of the pipe connections at the injectors. When fuel appears, tighten and recrank the engine.
Turn the bleed screw enough for the fuel to drip from the fuel gallery of the fuel injection pump. The engine will run but will not start again unless the bleed screw is loosened enough.
Ensure you follow the correct sequence. Refer to the operator's manual if you have one.
Some users have reported issues with the tractor not starting after running out of fuel, dying while running, and fuel leaks.
