Adding an auxiliary fuel tank significantly extends your vehicle's range, a crucial advantage for long-distance travel, off-road adventures, or situations with limited fuel access. However, simply installing a tank isn't enough; you need a reliable auxiliary fuel tank pump kit to transfer fuel efficiently and safely. This guide delves into everything you need to know about these kits, helping you make an informed decision for your specific needs.
What is an Auxiliary Fuel Tank Pump Kit?
An auxiliary fuel tank pump kit is a system designed to transfer fuel from an additional tank to your vehicle's main fuel tank. It typically includes a pump, hoses, wiring, filters, and potentially a control switch. The kit's components work together to ensure a smooth and consistent fuel flow, preventing issues like airlocks or fuel starvation. The type and complexity of the kit will vary depending on the vehicle and tank setup.
What are the Different Types of Auxiliary Fuel Tank Pump Kits?
Several types of auxiliary fuel tank pump kits cater to different needs and vehicle types:
-
Electric Pumps: These are the most common type, using an electric motor to draw fuel from the auxiliary tank. They are relatively easy to install and offer good control over fuel flow.
-
Mechanical Pumps: Driven by the engine's movement, these pumps are generally simpler and require less electrical wiring. However, they might be less efficient and require more maintenance than electric pumps.
-
Gravity-Fed Systems: In some cases, the auxiliary tank is positioned high enough that gravity alone can feed fuel to the main tank. This is a low-cost solution but isn't practical for all vehicle setups.
-
Kits with Integrated Filters: Many kits include a fuel filter to prevent debris from contaminating your vehicle's fuel system. This is a crucial element for protecting your engine.
-
Kits with Control Switches: These allow you to manually switch the pump on and off, giving you precise control over fuel transfer.
How Do I Choose the Right Auxiliary Fuel Tank Pump Kit?
Selecting the appropriate kit hinges on several factors:
-
Vehicle Compatibility: Ensure the kit is designed for your specific vehicle's fuel system. Consider factors like fuel type (gasoline, diesel), fuel pressure requirements, and tank size.
-
Pump Capacity: The pump's flow rate (gallons per hour or liters per hour) should be sufficient for your needs, considering both the tank size and your driving style.
-
Installation Complexity: Assess your mechanical skills. Some kits are easier to install than others. Opt for a kit that aligns with your experience level.
-
Budget: Kits vary widely in price, depending on features, quality, and brand. Set a budget before you begin your search.
What are the Benefits of Using an Auxiliary Fuel Tank Pump Kit?
-
Extended Range: The most significant benefit is the increased driving range, reducing the frequency of refueling stops.
-
Cost Savings: Potentially fewer fuel stops can lead to cost savings, especially on long trips.
-
Peace of Mind: Having extra fuel on hand offers peace of mind, particularly in remote areas or emergency situations.
-
Increased Capacity for Specific Needs: Useful for those who tow, haul heavy loads, or frequently travel in areas with limited fuel stations.
How Do I Install an Auxiliary Fuel Tank Pump Kit?
Installing an auxiliary fuel tank pump kit requires careful planning and execution. Consult the kit's specific instructions, but general steps usually include:
-
Secure the Auxiliary Tank: Properly mount and secure your auxiliary tank to your vehicle.
-
Route the Fuel Lines: Carefully run the fuel lines from the auxiliary tank to the main tank, ensuring secure connections and proper sealing.
-
Connect the Wiring: Connect the pump's wiring to your vehicle's electrical system, following the kit's instructions precisely. This often involves connecting to a suitable power source (fuse box) and potentially installing a switch.
-
Prime the System: Before starting the engine, prime the system to remove air from the lines.
-
Test the System: Carefully test the system's functionality to ensure the fuel is flowing properly.
What are Common Problems with Auxiliary Fuel Tank Pump Kits?
Potential issues include faulty pumps, leaking connections, clogged filters, or incorrect wiring. Regular maintenance, proper installation, and using high-quality components can help minimize these problems.
Where Can I Buy an Auxiliary Fuel Tank Pump Kit?
Auxiliary fuel tank pump kits are available from various sources, including online retailers, automotive parts stores, and specialized off-road equipment suppliers. Research different brands and read customer reviews to make an informed choice.
This comprehensive guide provides a solid foundation for understanding and selecting the right auxiliary fuel tank pump kit. Remember to prioritize safety, consult professional advice if needed, and always refer to the manufacturer's instructions for specific installation and operation details.
