Branson tractors are known to have issues with air in the fuel system, which can cause the engine to not start. This is a common problem with diesel engines and can usually be fixed by bleeding the fuel lines. The process of bleeding the fuel lines involves removing air from the fuel system by loosening the injector lines and allowing the fuel to flow until all the air is removed. This can be done by following specific procedures outlined in the tractor's manual or through general methods shared by other Branson tractor owners.
How to Bleed Branson Fuel Lines
| Characteristics | Values |
|---|---|
| Fuel filter | Ensure it is full; on some diesels, it is large and takes time to refill |
| Injector lines | Loosen until a steady stream of fuel comes out without bubbles, then re-tighten |
| Fuel injection nuts | Crack open about 1/3 turn, then re-tighten |
| Throttle | Push to full before cranking |
| Engine | Crank for a bit and look for fuel instead of air |
| Fuel pump cock | Open, start the engine, let it run, then close |
| Sight bowl nut | Loosen to let air out, then tighten back up |
| Hollow bolt | Hold with a 15mm wrench |
| Bleeder bolt | Loosen with a 12mm wrench, then tighten while the pump is running |

What You'll Learn
Ensure the fuel filter is full
Bleeding the fuel lines of a Branson tractor is a common maintenance task. It is necessary when air gets trapped in the fuel system, which can happen when you run out of fuel, disturb the fuel system, or change the fuel filter. This air prevents the engine from receiving fuel, causing difficulty in starting the engine or even making it impossible to start.
To ensure the fuel filter is full, start by turning off the engine and removing the ignition key from the cylinder. Locate the fuel filter and check if it has a built-in bleeder screw. If it does, position a clean rag or towel beneath the bleeder screw to catch any fuel spills. Then, using a wrench or bleeder screw key, slowly loosen the screw in a counterclockwise direction.
If your fuel filter does not have a bleeder screw, you may need to loosen the injector lines until you achieve a steady flow of fuel without any air bubbles. On some Branson tractors, the fuel filter is quite large and may take a significant amount of time to fill. Be patient and allow the filter to fill completely.
Once the fuel filter is full and there is a steady stream of fuel without air bubbles, tighten the injector lines and crank the engine. The fuel flow may not be consistent at first, and you may observe a pulsing effect. Continue cranking the engine and look for signs of fuel instead of air. Finally, re-tighten the injector line nuts, start the engine, and reduce the throttle setting.

Loosen the injector lines
To loosen the injector lines, you must first ensure the fuel filter is full. On some diesel engines, the filter is large and can take a long time to fill. Once full, you can begin to loosen the injector lines.
Turn the injector line nuts on the fuel lines by about a third. The fuel will not run smoothly; it will pulse. At this point, crank the engine for a while and look for fuel instead of air. You are looking for a steady stream of fuel without bubbles. Once you have this, you can move on to the next step.
Now, tighten the injector line nuts again and start the engine. You should also reduce the throttle setting at this point. If your engine doesn't start, it could be due to a dead battery or a bad starter.
If you have fuel flowing to the injector pump, be sure to do a pressure check before you crack the lines to the injectors.

Check for a constant stream of fuel
Bleeding the fuel lines on a Branson tractor is a straightforward process, but it requires attention to detail and some mechanical know-how. Here is a step-by-step guide to checking for a constant stream of fuel while bleeding Branson fuel lines:
First, ensure the fuel filter is full. Branson tractors, like many diesel engines, have large fuel filters that can take a significant amount of time to fill. A full fuel filter ensures that the engine has an adequate fuel supply during the bleeding process.
Next, locate the injector lines and loosen them carefully. You may need to use a wrench to loosen the injector bolts. Once the injector lines are loose, pay close attention to the fuel flow. Your goal is to achieve a steady stream of fuel without any air bubbles or pulsations. This step may take some time, so be patient and keep an eye on the fuel lines.
As the fuel begins to flow steadily, you can start to tighten the injector lines gradually. It is important to do this slowly and carefully to avoid overtightening, which can cause damage to the fuel lines and injector components.
Once all the injector lines are tight, it's time to crank the engine. With the fuel lines bled and a constant stream of fuel established, the tractor should start without issue. If the engine still struggles to start, repeat the process, ensuring that you take your time and follow each step precisely.
In some cases, you may need to employ the "spin, crack, and bleed" method, which involves using a hand primer plunger to establish fuel flow and pumping it until you feel resistance or hear fuel flowing back into the fuel tank through the return line. This method may be necessary if the tractor still fails to crank after bleeding the fuel lines.

Tighten the injector lines
To tighten the injector lines, it is important to first ensure that the fuel filter is full. On some diesel engines, the filter is quite large and can take a significant amount of time to fill up. Once the filter is full, the next step is to loosen the injector lines. Keep them loose until you achieve a steady stream of fuel without any bubbles. This process of bleeding air out of the fuel filter can be done using the bleeder screw on top of the canister or at the injection pump. This is a simple gravity-based operation.
When the fuel starts appearing, it is time to re-tighten the bolt. After tightening the bolt, the next step is to crack the fuel injection nuts on the fuel lines. Open them by about one-third of a turn. Then, push the throttle to full and crank the engine. The fuel flow will not be steady and will pulse instead. At this point, you should crank the engine for a while and look for fuel instead of air. Once you have confirmed the presence of fuel, you can re-tighten the injector line nuts.
Now, start the engine and reduce the throttle setting. If your engine does not crank, it could be due to a dead battery or a faulty starter. To address this, back off the injectors while cranking. Continue doing so until you achieve a constant stream of fuel without any air bubbles. After reaching this stage, tighten the injectors back up. Finally, crank the engine again, and it should start successfully.
It is important to note that the injector pump should bleed itself once you have fuel pressure. Therefore, you might not need to break the paint on the injector lines. However, if you do need to crack the lines, be sure to perform a pressure check before doing so to avoid any issues.

Crank the engine
Cranking the engine is the final step in bleeding Branson fuel lines. Before you get to this stage, you will have checked that the fuel filter is full and loosened the injector lines until there is a steady stream of fuel without bubbles.
Now, with the fuel flow established, open the throttle to full and crank the engine. The fuel will pulse rather than run steadily. Crank for a bit and then look for fuel instead of air. Once you see fuel, re-tighten the injector line nuts, start the engine, and reduce the throttle setting.
If you have a Branson tractor, you may need to remove the fuel filter and refill and loosen the two fuel lines at the injector connection (not at the pump). Then, crank the engine over until it starts or you get fuel flow, tighten the lines, and restart.
If you have fuel flowing to the injector pump, you may not need to break the paint on the injector lines. The injector pump should bleed itself once you have fuel pressure (after cranking a bit).

Frequently asked questions
To bleed Branson fuel lines, you need to remove air from the system. First, ensure the fuel filter is full. Then, loosen the injector lines until fuel comes out without any bubbles. Re-tighten the bolt and then crack the fuel injection nuts on the fuel lines. Push the throttle to full and crank the engine. Finally, tighten the injector line nuts, start the engine and reduce the throttle setting.
You will need a 15mm wrench to hold the hollow bolt and a 12mm wrench to loosen the bleeder bolt.
This method involves unscrewing the hand primer plunger and pumping the primer until it feels firm. You may hear the fuel flowing back into the fuel tank through the return line.
If your Branson tractor is not starting, it could be because there is air in the fuel lines. Check the fuel filter glass – if it is only half full, there is likely air in the system.
The simplest way to bleed Branson fuel lines is to open the cock on the fuel pump and let the engine run for a while. Then, close the fuel pump cock.
