Adding an auxiliary fuel tank significantly extends your vehicle's range, making it ideal for long journeys, off-road adventures, or situations where fuel stations are scarce. However, simply installing the tank isn't enough; you need a reliable auxiliary fuel tank pump kit to transfer fuel efficiently and safely. This guide explores everything you need to know about these kits, helping you choose and install the right one for your needs.
What is an Auxiliary Fuel Tank Pump Kit?
An auxiliary fuel tank pump kit is a complete system designed to transfer fuel from your auxiliary tank to your vehicle's main tank. It typically includes a fuel pump, wiring harness, switches, filters, hoses, and all the necessary fittings for a seamless installation. The quality of these components varies significantly, affecting both performance and longevity. Choosing a reputable brand is crucial for ensuring reliability and safety.
What are the Different Types of Auxiliary Fuel Tank Pump Kits?
Several types of auxiliary fuel tank pump kits cater to various vehicles and applications:
-
Electric Pumps: These are the most common type, powered by your vehicle's electrical system. They're generally quieter and easier to install than mechanical pumps. Electric pumps can be further categorized by their voltage (12V or 24V) and flow rate (measured in gallons per hour or liters per hour).
-
Mechanical Pumps: These pumps are driven by engine power, usually through a gear or belt system. They are generally more robust and less susceptible to electrical issues, but they can be noisier and more challenging to install.
How Do I Choose the Right Auxiliary Fuel Tank Pump Kit?
Selecting the right kit involves considering several key factors:
-
Vehicle Compatibility: Ensure the kit is compatible with your vehicle's fuel type (gasoline, diesel), fuel system pressure, and tank size. Check the manufacturer's specifications carefully.
-
Pump Capacity: The pump's flow rate should match or exceed the fuel consumption rate of your vehicle, especially under heavy load or high-speed driving. A larger capacity pump might not necessarily be better if it exceeds your tank’s capacity or your vehicle’s fuel system's requirements.
-
Safety Features: Look for kits with safety features like built-in pressure relief valves and thermal overload protection to prevent overheating or over-pressurization.
-
Installation Ease: While professional installation is always recommended, some kits are designed for easier DIY installation than others.
How Much Does an Auxiliary Fuel Tank Pump Kit Cost?
The cost of an auxiliary fuel tank pump kit varies greatly depending on the brand, features, and pump capacity. You can find basic kits for a few hundred dollars, while more advanced kits with higher flow rates and additional safety features can cost considerably more.
Where Can I Buy an Auxiliary Fuel Tank Pump Kit?
Auxiliary fuel tank pump kits are available from various sources, including:
-
Online Retailers: Amazon, eBay, and specialized automotive parts websites offer a wide selection.
-
Automotive Parts Stores: Local auto parts stores often carry a range of kits, allowing for in-person consultation with knowledgeable staff.
-
Truck and RV Accessory Stores: These stores often specialize in larger capacity kits suitable for trucks and RVs.
What are the Common Problems with Auxiliary Fuel Tank Pump Kits?
While generally reliable, some common issues include:
-
Pump Failure: This can be due to wear and tear, debris in the fuel, or electrical problems.
-
Hose Leaks: Improper installation or damaged hoses can lead to fuel leaks.
-
Wiring Issues: Loose connections or damaged wiring can prevent the pump from functioning correctly.
How Do I Install an Auxiliary Fuel Tank Pump Kit?
Installing an auxiliary fuel tank pump kit is a moderately challenging task, requiring some mechanical aptitude. While detailed instructions are included with most kits, professional installation is often recommended to ensure proper functioning and safety. Improper installation can lead to fuel leaks or damage to your vehicle's fuel system.
What Maintenance Does an Auxiliary Fuel Tank Pump Kit Need?
Regular maintenance can extend the life of your auxiliary fuel tank pump kit:
-
Inspect Hoses Regularly: Check for cracks, leaks, or kinks.
-
Clean or Replace Filters: This will prevent debris from clogging the pump.
-
Check Wiring Connections: Ensure all connections are secure and free from corrosion.
This comprehensive guide should provide a solid foundation for your understanding of auxiliary fuel tank pump kits. Remember to always prioritize safety and choose a kit that meets your specific needs and vehicle requirements. If you are unsure about any aspect of installation or maintenance, seek professional assistance.
