The Bobcat 763 is a popular skid steer loader known for its versatility and reliability in various construction, landscaping, and agricultural tasks. However, like any piece of heavy equipment, it is susceptible to occasional problems. One of the common issues some operators face is the machine acting like it runs out of fuel, even though the tank has fuel. This problem can be frustrating, as it not only affects work productivity but also raises concerns about potential underlying issues with the machine.
In this article, we’ll take a closer look at the potential causes of this problem, how to diagnose the issue, and the steps you can take to troubleshoot and resolve it.
Common Causes of the "Runs Out of Fuel" Issue
When a Bobcat 763 starts acting like it’s running out of fuel, but the tank is full, several issues could be at play. It's important to go through a systematic process of elimination to identify the exact cause. Here are the most common reasons why this might occur:
When troubleshooting an issue where the Bobcat 763 seems to run out of fuel, it’s important to go through a step-by-step diagnostic process. Here’s a basic approach:
If you’ve gone through all of these troubleshooting steps and the machine still acts as though it’s running out of fuel, it may be time to call in a professional mechanic. Issues with the fuel pump, electrical system, or other internal components might require specialized diagnostic tools and expertise to resolve. A professional technician will be able to pinpoint the issue and perform any necessary repairs.
Conclusion
The Bobcat 763 is a durable and reliable machine, but like any piece of heavy equipment, it requires regular maintenance and attention. When it starts acting like it runs out of fuel even with a full tank, it’s essential to diagnose the issue systematically. Checking for common problems such as fuel filter blockages, air in the lines, faulty pumps, and electrical issues can help you resolve the problem and get back to work faster.
Always keep up with routine maintenance, and address small issues before they become big problems. With the right care, your Bobcat 763 will continue to serve you reliably for years to come.

Common Causes of the "Runs Out of Fuel" Issue
When a Bobcat 763 starts acting like it’s running out of fuel, but the tank is full, several issues could be at play. It's important to go through a systematic process of elimination to identify the exact cause. Here are the most common reasons why this might occur:
- Fuel Delivery Problems
The fuel system is essential to ensure that fuel flows from the tank to the engine without interruption. A blockage or issue in the fuel delivery system is a typical cause of this problem. This could be due to a clogged fuel filter, fuel line restrictions, or even a malfunctioning fuel pump.
- Fuel Filter Blockage
Over time, the fuel filter can become clogged with debris and contaminants from the fuel tank. If the fuel filter is not regularly maintained or replaced, it may prevent proper fuel flow, causing the machine to stall or sputter as if it has run out of fuel.
- Air in the Fuel Lines
Air entering the fuel lines can disrupt the fuel delivery process, causing fuel starvation to the engine. This can happen if there is a fuel system leak or if the machine has been out of use for a while and the fuel lines need to be primed.
- Faulty Fuel Pump
The fuel pump is responsible for sending fuel from the tank to the engine. If the pump is malfunctioning, it may not deliver enough fuel to keep the engine running smoothly. A weak or damaged fuel pump can result in the machine losing power or shutting down unexpectedly.
- Contaminated Fuel
Contaminants in the fuel, such as water, dirt, or rust, can clog the fuel system and cause irregular operation. This can lead to the machine running out of fuel unexpectedly, even though the tank appears full.
- Electrical Issues (Fuel Solenoid)
The Bobcat 763 uses a fuel solenoid to control the fuel injection. If the solenoid is malfunctioning or the electrical connection is faulty, it can prevent the fuel from being properly delivered to the engine. This may cause the engine to act as though it is running out of fuel.
When troubleshooting an issue where the Bobcat 763 seems to run out of fuel, it’s important to go through a step-by-step diagnostic process. Here’s a basic approach:
- Check the Fuel Tank and Fuel Gauge
Ensure that the fuel tank is full and the fuel gauge is working correctly. Sometimes, the problem might be as simple as a faulty gauge reading incorrectly.
- Inspect the Fuel Filter
Inspect and replace the fuel filter if it looks dirty or clogged. A clogged fuel filter can severely restrict fuel flow and lead to power loss or engine stalling.
- Examine the Fuel Lines
Look for any visible signs of damage or leaks in the fuel lines. If you find any cracks or leaks, replace the affected parts. If the fuel lines are clear, ensure there is no air trapped in the system. If necessary, prime the system to remove any air pockets.
- Test the Fuel Pump
Listen to the fuel pump when you turn on the machine. If you don’t hear the pump priming, it could be a sign that it’s not working properly. Testing the fuel pressure with a gauge can also help confirm if the pump is operating at the correct pressure.
- Check for Contaminated Fuel
If the fuel tank has been sitting for a long time or the fuel appears cloudy, it may be contaminated with water or debris. Drain the fuel tank, clean the tank if needed, and refill it with fresh fuel. Replace the fuel filter to ensure contaminants don’t get into the system.
- Inspect the Electrical Connections
Check the fuel solenoid and its electrical connections. A loose or corroded connection could cause intermittent fuel delivery. If the solenoid appears to be malfunctioning, consider replacing it.
- Fuel System Priming: If the Bobcat 763 has recently had a fuel system service or a filter replacement, air may have entered the system. Always remember to prime the fuel system after any repairs involving the fuel lines or filters.
- Fuel Quality: Low-quality or old fuel can cause similar symptoms. Always use fresh, high-quality fuel, especially for older machines.
- Maintenance Records: Make sure that your machine is up to date on regular maintenance, especially fuel system checks. A well-maintained machine is less likely to have issues with fuel delivery.
If you’ve gone through all of these troubleshooting steps and the machine still acts as though it’s running out of fuel, it may be time to call in a professional mechanic. Issues with the fuel pump, electrical system, or other internal components might require specialized diagnostic tools and expertise to resolve. A professional technician will be able to pinpoint the issue and perform any necessary repairs.
