What You'll Learn
Check the fuel tank screen
To check the fuel tank screen of your Bobcat T250, you will need to locate the fuel primer bulb hose inside the fuel tank. This can be challenging to access, as some hoses may be located in a difficult-to-reach area. You may need to use tools such as a long pair of needle-nose pliers or a long screwdriver to help pry the hose out.
Once you have located the hose, you will need to remove it from the fuel tank. This may involve removing the drive hoses to create more room to work with. With the hose removed, you can now inspect the fuel tank screen, which is located at the bottom of the hose.
The fuel tank screen can become clogged with debris and contaminants over time, leading to fuel flow issues and engine performance problems. It is important to regularly clean the screen to ensure optimal fuel flow and engine performance.
To clean the fuel tank screen, you can use a variety of methods, such as:
- Using a brush or compressed air to remove any debris or buildup on the screen.
- Soaking the screen in a solvent or cleaning solution to dissolve any stubborn contaminants.
- Gently scrubbing the screen with a soft-bristled brush and warm, soapy water to remove any remaining residue.
It is important to ensure that the fuel tank screen is thoroughly cleaned and free of any debris before reinstalling it in the fuel tank. A clogged fuel tank screen can cause the fuel primer bulb to collapse and starve the engine of fuel, leading to performance issues and potential damage.

Use a hand vacuum pump to check for fuel
To clean out a Bobcat T250 fuel tank, you can use a hand vacuum pump to check for fuel. This is a diagnostic tool used to assess the performance and operational efficiency of a vehicle's fuel pump.
Firstly, locate the vacuum-operated pet cock. This is usually found on the vacuum line that leads to one of the intake ports. Remove this line and place it in a container to catch any fuel. This will help you determine if fuel is flowing as it should.
Next, stick the inlet line into a container of gas. This step ensures that there is an unrestricted inlet for the fuel. Now, crank the engine over. If the fuel pump is functioning correctly, you should see fuel being pumped out.
If there is no fuel being pumped out, the next step is to check the vacuum line. Ensure that it is properly connected. A well-functioning fuel pump and vacuum system are crucial for a smooth and efficient driving experience.
Additionally, it is important to regularly inspect and maintain your fuel pump and vacuum system. Common signs of a failing fuel pump include difficulty starting the engine, sputtering during acceleration, and stalling at high temperatures. By being proactive in your vehicle maintenance, you can avoid potential safety risks and enjoy a smoother ride.

Remove the primer bulb hose
To remove the primer bulb hose from your Bobcat T250, you'll need to first locate the hose. This can be a challenging task, as some have noted that it is almost impossible to reach and see the hose. You may need to use a flashlight and a mirror to try and locate it. Once you have a general idea of where the hose is, you can attempt to access it.
You may need to raise the cab to gain better access. If you have a long pair of needle-nose pliers, they can be useful for reaching the hose. Additionally, a long screwdriver can help you pry the fitting out. You may also need to remove the drive hoses to create more room to work.
Once you have better access to the hose, you can start by removing any components that may be blocking your path to the hose. This may include the fuel line, the primer ball, or the 90-degree fitting and rubber bushing that the hose connects to. Be careful when removing these components, as you don't want to damage any parts that can be reused.
When you have a clear path to the hose, you can start to carefully remove it. Be gentle, as you don't want to damage any surrounding components or the hose itself. If the hose is still in good condition, you may be able to reuse it after cleaning. If not, you may need to purchase a new hose as a replacement.
Remember, if you feel uncomfortable or unsure about any part of this process, it's always best to consult a professional or a Bobcat dealer for assistance. They will have the expertise and experience to guide you through the process or perform the necessary repairs.

Clean the fuel screen
To clean the fuel screen of a Bobcat T250, you will first need to locate the fuel pick-up tube and the primer bulb hose. This can vary across models, but generally, you will need to raise the cab and locate the pick-up tube, which is usually between the pumps and engine.
Once you have located the pick-up tube, the next step is to access the fuel screen. To do this, you will need to remove the 90-degree fitting and rubber bushing where the pick-up hose goes into the tank. You will then find a hose with the screen at the bottom. Use a long pair of needle-nose pliers or a long screwdriver to help pry the fitting out, and if necessary, remove the drive hoses to create more room.
It is important to note that you should not blow compressed air back through the hose as the screen has a check ball that can be blown off inside the tank. Instead, gently remove the screen for cleaning. You can use a hand vacuum pump to determine if the screen is plugged and needs cleaning.
To clean the fuel screen, you can use a mild detergent or fuel system cleaner, ensuring that you follow the instructions on the product carefully. It is important to allow the screen to dry completely before reassembling. Additionally, some operators have shared their experiences with shortening the hose to keep it away from the bottom of the tank, where debris and contaminants may collect.

Shorten the hose to keep it off the tank bottom
To clean out a Bobcat T250 fuel tank, you'll need to access the primer bulb hose inside the fuel tank. This can be difficult, as it's located in a tight space. However, you may be able to reach it using long needle-nose pliers or a long screwdriver to pry the fitting out. You might also need to remove the drive hoses to create more room to work.
Once you've accessed the primer bulb hose, you'll need to remove it from the fuel tank. This involves finding where the pickup hose goes into the tank and then pulling out the 90-degree fitting and rubber bushing. This will expose a hose with a screen on the bottom.
The screen on the fuel pickup line can become clogged, causing the primer bulb to collapse and the engine to starve. To address this, you'll need to clean the screen. However, simply cleaning the screen may not be enough, as it can quickly become clogged again.
To prevent the screen from becoming clogged, you can shorten the hose to keep it off the tank bottom. This involves cutting a couple of inches off the hose so that it sits higher in the fuel tank and doesn't come into contact with the debris that settles at the bottom. By shortening the hose, you can help to ensure that the screen remains clear and the primer bulb functions properly.
Shortening the hose is a straightforward process, but it requires careful measurement and precision to ensure the hose is trimmed to the correct length. It's important to measure twice and cut once, as you cannot add length back to the hose if it's cut too short. You'll also need to ensure that the hose is securely reattached to the 90-degree fitting and rubber bushing to prevent leaks.
