Unfastening the Seat

To begin the process of removing the fuel tank from your Pulsar motorcycle, you'll need to start by unfastening the seat. Here's a detailed, step-by-step guide on how to do just that:

Begin by locating the seat locking mechanism, which is typically positioned beneath the seat itself, close to the fuel tank. This locking mechanism ensures the seat remains securely fastened to the motorcycle. You'll need to disengage this lock to initiate the process of seat removal.

Take note of the positioning of the seat locking mechanism, as it will vary slightly depending on your Pulsar model. Newer models often feature a single locking mechanism positioned centrally, while older versions may have two separate locks located on either side of the seat. Understanding the layout of your particular model is essential for efficient disassembly.

Once you've identified the locking mechanism, the next step is to unlock it. Using your key, insert it into the designated keyhole, which should be clearly visible. Turn the key in a clockwise direction to unlock the seat. On some models, you may need to lift the seat slightly while turning the key to disengage the locking mechanism fully.

With the seat unlocked, you can now proceed to lift it off the motorcycle. Exercise caution during this step, as the seat may be attached to other components, such as the fuel tank, via cables or wires. Gently lift the seat, being mindful of any connected parts, and place it safely aside, ensuring it is clear of the fuel tank and any other components that may be affected during the tank removal process.

At this point, it's important to inspect the area beneath the seat to gain a clear understanding of the fuel tank's attachments and connections. You'll likely observe wires or cables connecting the fuel tank to the motorcycle's electrical system, and possibly other mechanical connections as well. Gaining a comprehensive visual understanding of these connections will help you plan the next steps of fuel tank removal efficiently and safely.

By following these steps, you've successfully unfastened and removed the seat of your Pulsar motorcycle, providing clear access to the fuel tank and its associated components. This careful and methodical approach ensures a safe and efficient process, reducing the risk of damage to your motorcycle and its parts. With the seat out of the way, you can now proceed to the next steps of removing the fuel tank.

Detaching the Fuel Line

To detach the fuel line from your Pulsar motorcycle, you'll need to follow a careful and methodical process to ensure no damage is caused and any safety hazards are avoided. Start by locating the fuel line, which runs from the fuel tank to the engine. It is usually secured with a clamp or a quick-disconnect fitting. Get a good view of the fuel line and the surrounding area, ensuring you have adequate lighting if working at night or in a dimly lit space. Now, carefully place a rag or cloth around the fuel line connection to absorb any spilled fuel. This is important to avoid any potential fire hazards.

Next, you'll want to relieve the pressure in the fuel line. This is a crucial step to avoid any spraying of fuel when you detach the line. To do this, locate the schrader valve on the fuel line, usually found near the fuel pump. Depress this valve with a small screwdriver to release the pressure. You may need to wear protective gloves and eye protection for this step. Once the pressure is released, you can proceed to disconnect the fuel line. If your Pulsar uses a clamp to secure the fuel line, use a screwdriver to loosen the clamp, being careful not to strip the screws.

Then, gently pull the fuel line away from the tank. If your motorcycle uses a quick-disconnect fitting, depress the tab on the fitting with your thumb and pull the line away from the tank. In some cases, you may need to use a flat-head screwdriver to gently pry the fitting loose, but take care not to damage the connector. Once the fuel line is detached, immediately plug or cap the open end to prevent any dirt or debris from entering the line and causing issues when you reinstall the tank.

Finally, be sure to store the detached fuel line safely and securely. It's a good idea to hang it up or coil it neatly to avoid any kinks or damage. This process ensures that you can safely and effectively detach the fuel line when removing the fuel tank from your Pulsar motorcycle. Always remember to take your time, wear appropriate protection, and have the necessary tools on hand before beginning any work.

Removing the Fuel Tank Mounting Brackets

To remove the fuel tank from a Pulsar motorcycle, you'll typically need to begin by disconnecting the tank from the fuel lines and hoses, and then lifting it up and out of the motorcycle frame. However, before you can do that, you must first remove the fuel tank mounting brackets, which secure the fuel tank in place. Here's a step-by-step guide on how to remove the fuel tank mounting brackets:

Begin by locating the mounting brackets. On most Pulsar motorcycles, there are usually two mounting brackets – one on each side of the fuel tank. These brackets are typically bolted to the frame and may have rubber bushings or isolators to reduce vibration.

Once you've located the mounting brackets, the next step is to remove the bolts securing them in place. Make sure you have a secure place to keep the bolts, as you'll need to put them back during reassembly. Typically, there will be two bolts per bracket, but this may vary depending on your Pulsar model. When removing the bolts, be careful not to strip the threads or drop them into the frame, as retrieval may be difficult.

With the bolts removed, you can now carefully lift the mounting brackets away from the fuel tank. Again, the exact process may vary slightly depending on your Pulsar model, but usually, the brackets will lift straight up and away from the tank. Be gentle and take note of any other components that may be attached to or near the mounting brackets, such as wiring harnesses or hoses, to avoid putting strain on them.

If the mounting brackets are stubborn and difficult to remove, it may be necessary to gently pry them away from the tank using a flat-head screwdriver or similar tool. Be very careful when doing this, as you don't want to damage the fuel tank or any surrounding components. Working slowly and gently is key.

Once the mounting brackets are removed, set them aside safely, taking care not to misplace them, as you'll need to reinstall them when you put the fuel tank back on. With the brackets removed, you should now be able to lift the fuel tank up and out of the frame, allowing you to access the fuel pump, sender unit, or any other components requiring maintenance or replacement.

Draining and Removing the Fuel Tank

Before removing the fuel tank from your Pulsar motorcycle, it is important to drain the fuel to avoid spills and reduce the risk of fire. Here is a step-by-step guide on how to safely drain and remove the fuel tank:

Begin by parking your Pulsar motorcycle on a flat, level surface, and ensure it is securely supported on its center stand or a sturdy motorcycle lift. Wear protective gear, including gloves and eye protection, to safeguard against any fuel spills or debris.

Locate the fuel petcock valve, typically found at the base of the fuel tank. Place a fuel container, such as a gas can or approved fuel storage container, below the petcock valve. Open the valve to start draining the fuel from the tank. Ensure that the area is well-ventilated to prevent the buildup of fumes.

You should now carefully remove the fuel tank cap to allow air to enter the tank and facilitate the draining process. If your Pulsar model has a reserve fuel tap setting, ensure it is set to the 'ON' or 'RES' position to ensure complete draining. Allow sufficient time for the fuel to drain completely. The time taken will depend on the fuel level in your tank.

Once the fuel has drained, close the petcock valve securely. You can now proceed with detaching the fuel lines and hoses connected to the fuel tank. Be cautious as residual fuel may still be present in these lines. It is recommended to use a fuel line disconnect tool or similar to avoid damage to the fittings. Place a rag or towel beneath the connections to absorb any residual fuel that may spill.

With the fuel drained and the lines disconnected, you can now safely remove the fuel tank from your Pulsar motorcycle. Refer to your owner's manual or a reliable online resource for specific instructions on detaching the fuel tank from the motorcycle's frame. Ensure you have a clear understanding of the process before proceeding, as it may involve multiple steps and the removal of additional components.

Final Checks and Reassembly

Before refitting the fuel pump, ensure that the eight bolts are tightened from inside the tank to prevent leaks. If you intend to reuse the original tank, it is recommended to unbolt the lower ring, clean it, and reseal it. This lower ring has eight bolts that hold it to the tank, and the bolt heads are inside the tank.

If the tank has surface rust, it is important to remove it before reassembly. To do this, fill the tank with water to eliminate any remaining petrol fumes, preventing explosions. Then, use a combination of tools such as a wire brush, sandpaper, or an angle grinder to eliminate the rust. Treat the rusted areas with a rust remover gel, and then prepare and paint the surface.

When reassembling the fuel tank, ensure the tank filler pipes are securely connected. If the old rubber filler hoses are bonded to the tank filler pipes, it is recommended to cut them off and replace them with new ones. Refit the hoses only after the tank has been replaced.

Additionally, pay attention to the cables under the car and their connection points to the gear mechanism. Note the position of the lock nut in relation to the throttle cable bracket to avoid adjusting the throttle position cable during reassembly. The throttle cable should be routed down the induction side of the engine for proper repositioning.

Finally, ensure the fuel tank is securely mounted and that all connections are tight to prevent leaks. Perform a test run and inspect for any leaks or abnormal behaviour.
