When the Bobcat S250 skid steer loader experiences a fuel tank leak, it can result in fuel spillage, affecting the machine's performance and safety. A fuel leak not only poses a safety hazard but also increases operating costs. Below are some diagnostic methods and solutions shared by users to help quickly identify and fix the issue.
Symptoms of Fuel Tank Leaks
The main symptom of a fuel tank leak is the presence of fuel stains on the ground, or visible fuel traces on the surface or around the fuel tank. A strong fuel odor may also be noticeable, especially during fueling or when the machine is in operation. Additionally, abnormal fuel consumption during operation could indicate a leak.
Diagnostic Steps
Fuel tank leaks in the Bobcat S250 skid steer loader are common but can be easily diagnosed and fixed by inspecting key components such as the fuel tank, lines, pump, and fill cap. Promptly addressing fuel leaks will help improve machine safety and efficiency, while preventing additional repair costs and safety hazards.

Diagnostic Steps
- Inspect the Fuel Tank: Start by inspecting the external surface of the fuel tank for any cracks or damage. In some cases, the fuel tank may develop cracks or holes due to impacts, corrosion, or aging. Pay close attention to seams, welds, and the fuel fill cap area to check for leaks.
- Examine Fuel Lines and Fittings: Fuel lines and fittings are common sources of leaks. Inspect the fuel lines for any cracks, wear, or signs of aging. Ensure that all fittings are tightly secured and free from corrosion. Loose fittings can cause fuel leaks, especially in high-pressure environments.
- Check the Fuel Pump and Filter: The fuel pump and filter area may also be where the leak originates. Check the fuel pump for any leaks, particularly around the fittings. If the fuel filter is old or damaged, it may lead to fuel leakage, affecting fuel flow.
- Inspect the Fuel Fill Cap: If the fuel fill cap is not properly sealed, it could cause fuel overflow or leakage. Check the fuel cap's seal to ensure it is intact. If the seal is worn or damaged, replace it promptly.
- Repair or Replace the Fuel Tank: If the fuel tank has visible cracks or holes, you can use a professional fuel tank repair kit for temporary repairs. However, if the damage is severe, replacing the entire fuel tank is recommended.
- Replace Fuel Lines and Fittings: If the fuel lines are cracked or worn, replace them with new ones. Tighten all fuel line fittings to ensure they are secure and free from leaks.
- Repair or Replace the Fuel Pump and Filter: If the fuel pump or filter is damaged, replace them with new components. Cleaning or replacing the filter will help restore proper fuel flow.
- Replace the Fuel Fill Cap Seal: If the fuel fill cap seal is worn or damaged, replace it to prevent fuel leaks.
