Water in the fuel tank can cause issues, requiring a purge of the system

Water in the fuel tank is a common issue for skid steers, especially if they have been sitting idle for a few months. This can cause the engine to shut off shortly after starting up. To address this issue, you will need to drain the fuel tank and clean the fuel system. Here is a step-by-step guide:

Step 1: Drain the Fuel Tank

Remove the fuel line to check for water in the line and tank. If you find water, empty the fuel tank completely. You can use a drill-powered pump to remove the water from the bottom of the tank, pumping it into a white bucket and allowing it to sit so you can see the water separate from the diesel. This will help you assess the level of contamination.

Step 2: Clean the Fuel System

Clean the fuel lines by blowing air back towards the tank to remove any debris. Replace and secure the lines. If your skid steer has a water separator, drain it and replace the fuel filters.

Step 3: Refill and Purge the System

Refill the tank with fresh diesel fuel and add the appropriate amount of diesel fuel tank cleaner. Replace the fuel cap and start the machine. Bleed your fuel system by cranking the engine until it starts. If your skid steer has injection pumps, open the bleeder screw to purge air.

Step 4: Additional Measures

Consider adding a clear, in-line fuel filter between the fuel tank and the pump to easily monitor and clean out any water buildup. You may also want to add an additional water fuel separator until you have purged all the water from the system. Regularly purge filters to prevent water buildup.

Water in the fuel tank can cause significant issues, so it is important to address the problem as soon as possible and take preventative measures to avoid recurrence.

Fuel transfer pumps are available for refuelling, but some prefer a simple gravity feed tank

The fuel consumption of a skid steer loader depends on the age of the machine and the wear on the engine. On average, it consumes 2.7 gallons per hour. For instance, the Bobcat S 650, a new skid steer loader, runs for around 6 hours a day.

When it comes to refuelling, fuel transfer pumps are available, but some prefer a simple gravity feed tank. Gravity feed tanks are a simple and effective solution, especially for older machines. They are also cost-effective, as they are much cheaper than transfer pumps. However, safety concerns have been raised about gravity feed systems, including the possibility of fuel leaks, and violations of US DOT regulations. Transfer Flow, a manufacturer of refueling tanks, has expressed concerns about the safety and legality of gravity feed systems, stating that they may adversely affect vehicle diagnostic systems and potentially cause fires if the main tank is overfilled.

On the other hand, gravity feed systems have been successfully used in boats and trucks, with some users opting for gravity feed auxiliary tanks to filter fuel and keep their engines clean. The use of gravity feed systems in trucks has even passed D.O.T inspections, despite potential safety concerns.

Ultimately, the choice between a fuel transfer pump and a gravity feed tank depends on various factors, including cost, convenience, and safety considerations. While gravity feed tanks are simpler and more cost-effective, fuel transfer pumps may offer greater peace of mind in terms of safety and regulatory compliance.

Fuel tank placement and refuelling methods depend on user preference and convenience

Fuel tank placement and refuelling methods for a skid steer depend on user preference and convenience. Some users opt for a small, rechargeable jump box instead of wiring the fuel tank to the battery. This provides flexibility in terms of fuel tank placement, as it can be moved with the skid steer and kept on-site.

Another option is to use a fuel transfer pump to transfer fuel from a truck's diesel tank. This eliminates the need to fill up individual containers and can be achieved using a small transfer tank with a 12v pump.

For those who prefer to keep their fuel tank in their truck, a transfer tank and pump setup can be mounted to a jet ski trailer. This saves bed space in the truck while still allowing for easy refuelling.

The fuel tank capacity of a skid steer should also be considered when determining placement and refuelling methods. For example, the bobcat fuel capacity is around 35 gallons, and the running hour is around 6 hours per day.

Additionally, the age of the machine and the wear on the engine can impact fuel consumption. On average, a skid steer may consume around 2.7 gallons per hour, but this can vary depending on the specific model and operating conditions.

Ultimately, the user's preference, convenience, and specific requirements will dictate the optimal fuel tank placement and refuelling methods for their skid steer.

Fuel pump issues can cause hard starts, with electric fuel pumps offering a potential solution

Fuel pump issues are a common problem for vehicles, and can cause difficulty starting the engine. Skid steers, for example, are known to experience fuel quality issues, such as water contamination, which can lead to hard starts or even engine shutdown shortly after starting.

The fuel pump is a critical component of a vehicle's fuel system, responsible for delivering fuel from the tank to the engine. When a fuel pump malfunctions or fails, it can lead to significant problems with the vehicle's performance and, in some cases, even render the vehicle inoperable.

There are several factors that can contribute to fuel pump issues. One of the most common issues is contaminated fuel, which can include dirt, debris, or water in the fuel tank. Water contamination, in particular, can cause hard starts or sudden engine shutdown, as water is heavier than diesel and can accumulate at the bottom of the tank, disrupting fuel delivery to the engine.

Another factor that can impact fuel pump health is the fuel level in the tank. Running a vehicle with low fuel levels can cause the pump to overheat. Fuel acts as a coolant for the pump, and consistently low levels can lead to increased temperatures, reducing the pump's lifespan and potentially causing complete pump failure.

Additionally, electrical issues can also lead to fuel pump problems. Faulty wiring, corroded connections, loose terminals, or damaged wiring can disrupt the consistent electrical current required for proper fuel pump operation. These issues can cause intermittent or complete power loss to the pump, impacting engine performance and start-up.

To address fuel pump issues and improve engine performance, several solutions can be considered:

  • Fuel Pump Replacement: This is often recommended when the pump is severely damaged or worn out. While this option may be costly upfront, it can prevent future breakdowns and potential damage to other engine components. Most fuel pumps are designed to last well past 100,000 miles under normal conditions.
  • Fuel Pump Repair: If the damage to the fuel pump is not severe, repairing it by replacing faulty parts may be a temporary solution. However, this may not address the underlying cause of the issue.
  • Fuel System Cleaning: Over time, carbon deposits and residues can build up in the fuel system, leading to reduced power, poor fuel economy, and potential engine damage. Regular fuel system cleaning, recommended every 15,000 miles, can help maintain optimal performance and prevent blockages.
  • Electric Fuel Pumps: Upgrading to an electric fuel pump, which is standard in modern cars, can offer improved durability and reliability. Electric fuel pumps work in tandem with fuel injection systems, enhancing fuel delivery and engine performance.
