The Bobcat 773 Skid Steer is a highly reliable and powerful machine used for a variety of construction and landscaping tasks. Like any heavy equipment, the Bobcat 773 requires regular maintenance to ensure optimal performance and longevity. One critical component of the Bobcat 773's operation is the fuel system, which includes the fuel lines. Over time, these fuel lines can become damaged or clogged, leading to fuel delivery issues, decreased engine performance, or even complete system failure.
This article will provide a detailed guide on the importance of maintaining the fuel lines on your Bobcat 773, signs of potential fuel line problems, and how to properly repair or replace damaged fuel lines.
Understanding the Fuel System of the Bobcat 773
Before diving into fuel line maintenance, it's important to understand how the fuel system on the Bobcat 773 works. The fuel system is responsible for delivering fuel from the tank to the engine. It consists of several components, including the fuel tank, fuel lines, fuel filter, fuel pump, and injectors.
The fuel lines themselves are responsible for transporting fuel from the tank to the engine. These lines are typically made of durable rubber or metal to withstand the pressure and temperature variations in the system. Over time, however, they can become worn out or damaged, which can cause fuel leaks, air entering the system, and poor engine performance.
Signs of Fuel Line Problems
Recognizing the early signs of fuel line issues can help you address the problem before it leads to more serious damage. Here are some common symptoms of faulty or damaged fuel lines:
1. Engine Stalling or Poor Performance
If you notice that your Bobcat 773 engine is stalling or running rough, it may be a sign of inadequate fuel delivery caused by a blocked or damaged fuel line. Fuel lines that are cracked or clogged can restrict fuel flow, leading to inconsistent engine performance.
2. Fuel Leaks
Visible fuel leaks near the fuel lines or fuel filter are a clear indication of a problem. Leaks can result from cracks or punctures in the fuel lines, and they pose a significant safety hazard. If you notice fuel pooling around the engine area or under the skid steer, stop using the equipment immediately and address the issue.
3. Fuel Odor
A strong smell of fuel while the engine is running can indicate a fuel leak, often caused by a damaged fuel line. It's crucial to investigate and repair the source of the odor to prevent further damage and avoid safety hazards.
4. Difficulty Starting the Engine
If your Bobcat 773 is having trouble starting, it could be due to air entering the fuel lines, which prevents the engine from getting the proper fuel-to-air mixture. This issue can be caused by cracks in the fuel lines or a failing fuel filter.
Repairing or Replacing Fuel Lines on the Bobcat 773
When it comes to maintaining the fuel lines on your Bobcat 773, there are two main options: repairing or replacing the damaged lines. Below are step-by-step instructions for both approaches.
1. Safety First
Before starting any repair or replacement work, it's crucial to take the necessary safety precautions. Always ensure the machine is turned off and the battery is disconnected to avoid any accidental starts. Additionally, relieve any fuel system pressure by disconnecting the fuel line from the fuel filter or pump. Make sure the area is well-ventilated to avoid inhaling fumes or causing a fire hazard.
2. Inspecting the Fuel Lines
Start by visually inspecting the fuel lines for any obvious signs of damage, such as cracks, holes, or fuel stains. You may need to move components or panels around the fuel lines to get a better view. If the lines are cracked or compromised, it's best to replace them entirely. In some cases, a temporary repair may be possible using specialized sealants or hose clamps, but it's always better to replace the damaged section if possible.
3. Replacing Damaged Fuel Lines
If the fuel lines on your Bobcat 773 are damaged beyond repair, here's how to replace them:
While replacing the fuel lines, it's also a good idea to check the condition of the fuel filter. A clogged or dirty fuel filter can contribute to fuel flow issues and cause similar symptoms. If the fuel filter appears dirty, replace it with a new one. Cleaning or replacing the fuel filter is a quick and easy way to improve fuel delivery and ensure the longevity of your engine.
Preventing Future Fuel Line Issues
Preventing damage to the fuel lines can save you time and money in the long run. Here are a few tips to keep the fuel lines on your Bobcat 773 in good condition:
Maintaining the fuel lines on your Bobcat 773 Skid Steer is essential for ensuring reliable engine performance and preventing costly repairs. Whether you're dealing with fuel leaks, poor engine performance, or difficulty starting the engine, addressing fuel line issues promptly can save you from more serious problems down the road.
By following the steps outlined above for inspecting, repairing, and replacing damaged fuel lines, you can keep your Bobcat 773 running smoothly and efficiently. Regular maintenance, along with proactive checks, will help prolong the life of your machine and reduce the frequency of costly breakdowns.

3. Replacing Damaged Fuel Lines
If the fuel lines on your Bobcat 773 are damaged beyond repair, here's how to replace them:
- Step 1: Remove the Old Fuel Lines
Using wrenches, disconnect the old fuel lines from the fuel filter, fuel pump, and injectors. Be prepared for some fuel spillage, so have rags or a pan ready to catch the excess fuel. Remove any clamps or brackets holding the fuel lines in place.
- Step 2: Measure and Cut the New Fuel Lines
Measure the length of the old fuel lines and cut the new fuel lines to match. Make sure to use fuel-resistant hose or tubing that is specifically designed for heavy machinery, as it can withstand the pressure and temperature of the system.
- Step 3: Install the New Fuel Lines
Install the new fuel lines in the same position as the old ones. Ensure that the lines are tightly secured to the fuel filter, fuel pump, and injectors using appropriate clamps. Be sure that the lines are routed properly to avoid any interference with moving parts.
- Step 4: Test the System
Once the new fuel lines are installed, reconnect the fuel system and check for leaks. Start the engine and monitor for any signs of fuel leakage, rough running, or stalling. If the engine runs smoothly and no leaks are detected, the replacement is complete.
While replacing the fuel lines, it's also a good idea to check the condition of the fuel filter. A clogged or dirty fuel filter can contribute to fuel flow issues and cause similar symptoms. If the fuel filter appears dirty, replace it with a new one. Cleaning or replacing the fuel filter is a quick and easy way to improve fuel delivery and ensure the longevity of your engine.
Preventing Future Fuel Line Issues
Preventing damage to the fuel lines can save you time and money in the long run. Here are a few tips to keep the fuel lines on your Bobcat 773 in good condition:
- 1. Regular Inspections: Check the fuel lines regularly for signs of wear or damage, especially if you operate in harsh conditions like extreme heat or cold, or in environments with dirt and debris.
- 2. Use Quality Fuel: Always use high-quality fuel that meets the manufacturer's specifications. Contaminated or low-quality fuel can cause blockages in the fuel lines and lead to other engine issues.
- 3. Keep the Fuel System Clean: Regularly replace the fuel filter and ensure that there is no debris or contaminants in the fuel system. This helps maintain the fuel flow and prevents strain on the fuel lines.
- 4. Protect the Fuel Lines: If possible, use protective sleeves or covers on the fuel lines to prevent damage from sharp objects or debris on the job site.
Maintaining the fuel lines on your Bobcat 773 Skid Steer is essential for ensuring reliable engine performance and preventing costly repairs. Whether you're dealing with fuel leaks, poor engine performance, or difficulty starting the engine, addressing fuel line issues promptly can save you from more serious problems down the road.
