Auxiliary fuel tank pump kits provide a crucial solution for extending the range of vehicles, particularly those used in demanding applications like farming, construction, or long-distance hauling. They offer the ability to seamlessly switch between main and auxiliary tanks, ensuring uninterrupted fuel supply. This comprehensive guide will delve into the essential aspects of auxiliary fuel tank pump kits, addressing common questions and concerns.
What is an Auxiliary Fuel Tank Pump Kit?
An auxiliary fuel tank pump kit comprises a pump, necessary wiring, tubing, and fittings designed to draw fuel from an additional fuel tank and deliver it to the vehicle's engine. This allows vehicles to carry significantly more fuel than their standard tank capacity, extending their operational range without frequent refueling stops. These kits are specifically engineered to integrate seamlessly with the existing fuel system, often including features like automatic switching between tanks or manual selection options. The complexity of the kit varies depending on the vehicle and the type of auxiliary tank used.
How Does an Auxiliary Fuel Tank Pump Kit Work?
The functionality is relatively straightforward. The pump, typically an electric submersible pump, is installed within the auxiliary fuel tank. When activated (either automatically or manually), the pump draws fuel from the tank and pushes it through the supplied tubing to a connection point in the main fuel system. This point varies depending on the vehicle's design; it might be integrated into the existing fuel line, or it might feed into a fuel filter or a dedicated fuel input point. Modern kits often include safety features like low-fuel sensors and pressure relief valves.
What are the Different Types of Auxiliary Fuel Tank Pump Kits?
Auxiliary fuel tank pump kits differ primarily in their activation method and their compatibility with specific vehicle makes and models.
- Electrically Operated Kits: These are the most common type, using an electric pump powered by the vehicle's electrical system. They can offer features like automatic switching between tanks based on fuel levels or manual switches allowing the driver to select the fuel source.
- Gravity-Fed Systems: While less common for long-range applications, gravity-fed systems rely on the elevation difference between the auxiliary tank and the main tank to transfer fuel. They are generally simpler and less expensive but often less efficient for larger tanks or tanks located significantly lower than the main tank.
- Vehicle-Specific Kits: Some kits are designed for specific vehicle models, ensuring a precise fit and seamless integration. These kits usually come with detailed instructions and often include all necessary parts and fittings.
- Universal Kits: Universal kits can be adapted to a range of vehicles but may require more modification and technical expertise during installation. Choosing the correct components and adapting them to your vehicle's fuel system is crucial for safety and proper operation.
How Do I Choose the Right Auxiliary Fuel Tank Pump Kit?
Selecting the right kit requires careful consideration of several factors:
- Vehicle Compatibility: Ensure the kit is compatible with your vehicle's fuel system, engine type, and fuel tank configuration.
- Tank Capacity: The pump's capacity should be appropriate for the size of the auxiliary tank. Oversized pumps might be unnecessary and could strain the fuel system, while undersized pumps may not provide sufficient flow.
- Fuel Type: The pump must be compatible with the type of fuel your vehicle uses (e.g., gasoline, diesel).
- Installation Difficulty: Consider your mechanical aptitude. Some kits offer simpler, plug-and-play installations, while others might require more advanced knowledge and tools.
- Safety Features: Look for kits that include safety features like low-fuel sensors, pressure relief valves, and proper electrical protection.
What are the Benefits of Using an Auxiliary Fuel Tank Pump Kit?
- Extended Range: The primary benefit is the significantly increased driving range before needing to refuel. This is crucial in remote areas or during long journeys.
- Increased Productivity: For work vehicles, extended range means less downtime spent refueling and more time spent on the job.
- Cost Savings: While the initial investment can be substantial, the reduced frequency of refueling can lead to long-term cost savings on fuel purchases.
- Peace of Mind: Knowing you have a larger fuel reserve provides peace of mind, especially during long trips or in areas with limited fuel availability.
Are There Any Potential Drawbacks?
- Increased Weight: The added weight of the auxiliary tank and fuel can impact fuel efficiency and handling.
- Installation Complexity: Installation can be challenging for individuals without mechanical experience. Improper installation could lead to fuel leaks or other safety hazards.
- Cost: The initial purchase price can be significant.
- Potential for Leaks: Faulty installation or components can lead to fuel leaks, posing a safety risk. Regular inspection and maintenance are essential.
This guide provides a comprehensive overview of auxiliary fuel tank pump kits. Remember to carefully research and select a kit that suits your specific needs and vehicle, and always prioritize safety during installation and operation. Consult a qualified mechanic if you have any doubts or lack the necessary expertise.
