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 refueling opportunities. However, simply installing the tank isn't enough; you need a reliable auxiliary fuel tank pump kit to effectively transfer fuel from the auxiliary tank to your main tank. This comprehensive guide explores 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 collection of components designed to transfer fuel from an additional fuel tank to your vehicle's engine. These kits typically include a fuel pump, wiring harness, filter, mounting brackets, hoses, and potentially other necessary fittings. The quality and components included can vary significantly between brands and models, so careful selection is essential. The pump itself is the heart of the system, responsible for moving fuel under pressure to the engine's fuel system.
How Does an Auxiliary Fuel Tank Pump Kit Work?
The system works by drawing fuel from the auxiliary tank using the pump. This fuel is then filtered to remove any debris before being sent through the hoses to the main fuel system of your vehicle. The kit often includes a switch to activate and deactivate the pump, giving you precise control over the fuel transfer process. Many modern kits incorporate safety features to prevent overfilling and ensure a smooth, reliable operation.
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 power the pump. They are generally easier to install and offer more flexibility in placement.
-
Mechanical Pumps: These pumps are driven mechanically, usually by a connection to the engine's drive shaft. They are typically less common due to the more complex installation requirements.
-
Kits for Specific Vehicles: Some kits are designed specifically for particular vehicles and fuel tank configurations, offering a seamless integration and a guaranteed fit. Others are more universal and can be adapted to various applications.
What are the Benefits of Using an Auxiliary Fuel Tank Pump Kit?
The primary benefit is the extended range of your vehicle. Other advantages include:
-
Increased Fuel Capacity: A significant increase in the amount of fuel you can carry allows for longer journeys without frequent refueling stops.
-
Improved Efficiency (in some cases): In certain situations, carrying more fuel can result in slight improvements in fuel efficiency.
-
Enhanced Preparedness: Having extra fuel can be crucial in remote areas, emergencies, or situations where fuel is scarce.
What Factors Should I Consider When Choosing an Auxiliary Fuel Tank Pump Kit?
Several key factors will influence your decision:
-
Vehicle Compatibility: Ensure the kit is compatible with your vehicle's fuel system and the type of auxiliary tank you're using.
-
Pump Capacity: Choose a pump with sufficient capacity to meet your needs. Higher capacity pumps may be needed for larger tanks or higher-demand engines.
-
Flow Rate: Consider the flow rate of the pump, as this determines how quickly the fuel will transfer.
-
Reliability and Durability: Opt for a kit from a reputable brand known for producing high-quality, reliable components that will withstand demanding conditions.
-
Safety Features: Look for kits with safety features such as overfill protection and pressure relief valves.
What are the Common Problems with Auxiliary Fuel Tank Pump Kits?
While generally reliable, some common issues include:
-
Pump Failure: Pumps can fail due to wear and tear, debris in the fuel, or electrical issues.
-
Leaks: Leaks can occur in the hoses, connections, or the pump itself.
-
Wiring Problems: Problems with the wiring harness can prevent the pump from functioning correctly.
How Do I Install an Auxiliary Fuel Tank Pump Kit?
Installation varies depending on the specific kit and vehicle. However, many kits come with comprehensive instructions. It is crucial to follow these instructions carefully and seek professional help if needed, especially if you are not mechanically inclined. Improper installation can lead to safety hazards and fuel leaks.
How Much Does an Auxiliary Fuel Tank Pump Kit Cost?
Prices vary widely depending on the brand, features, and components included in the kit. Expect to pay anywhere from a few hundred dollars to several thousand dollars, depending on the complexity and quality of the system.
Choosing the right auxiliary fuel tank pump kit requires careful consideration of your specific needs and vehicle type. By understanding the different types, features, and potential issues, you can make an informed decision and enjoy the benefits of extended fuel range and enhanced preparedness. Remember, safety should always be a top priority; if you have any doubts about the installation, seek professional assistance.
