Auxiliary fuel tank pump kits are becoming increasingly popular among off-road enthusiasts, long-haul truckers, and anyone needing to extend their vehicle's range. These kits provide the necessary components to effectively transfer fuel from an auxiliary tank to the main fuel system, significantly increasing your vehicle's driving distance before refueling. This comprehensive guide will delve into the key aspects of auxiliary fuel tank pump kits, answering common questions and providing valuable insights for potential buyers.
What is an Auxiliary Fuel Tank Pump Kit?
An auxiliary fuel tank pump kit is a collection of parts designed to facilitate the transfer of fuel from a secondary, or auxiliary, fuel tank to your vehicle's main tank. This typically includes a fuel pump (electric or mechanical), necessary tubing, wiring (for electric pumps), filters, mounting brackets, and potentially other components depending on the specific kit and vehicle application. The kit allows you to seamlessly switch between your main tank and the auxiliary tank, effectively doubling—or even tripling—your vehicle's range.
How Does an Auxiliary Fuel Tank Pump Kit Work?
The operation is relatively straightforward. The auxiliary fuel pump draws fuel from the auxiliary tank. This fuel then travels through the tubing, often passing through a filter to remove debris, and is then delivered either directly into the main fuel line or into the main fuel tank itself. The exact method depends on the specific design of the kit and the vehicle's fuel system. Electric pumps require a power source (usually a 12V connection), while mechanical pumps are driven by the vehicle's engine.
What are the Different Types of Auxiliary Fuel Tank Pump Kits?
Several types of kits cater to various needs and vehicle applications:
-
Electric Pump Kits: These are the most common type, offering flexibility in placement and easier installation. The pump is powered by the vehicle's electrical system, allowing for precise control and the ability to turn the pump on and off as needed.
-
Mechanical Pump Kits: These kits utilize a pump driven by the engine's power, eliminating the need for electrical connections. They are often simpler to install but might not offer the same level of control as electric pumps.
-
Gravity-Fed Kits: While not strictly a "pump" kit, gravity-fed systems utilize the height difference between the auxiliary and main tank to transfer fuel. These are generally the simplest but require careful tank placement and may not be suitable for all applications.
What are the Benefits of Using an Auxiliary Fuel Tank Pump Kit?
The primary benefit is the extended range. This is particularly crucial for long-distance travel, off-road adventures, or situations where refueling opportunities are limited. Other benefits include:
- Increased Fuel Capacity: Significantly expands your vehicle's fuel holding capacity.
- Cost Savings (Potentially): Buying fuel in bulk or at cheaper locations can offset the cost of the kit over time.
- Peace of Mind: Knowing you have a significant fuel reserve can be reassuring, especially in remote areas.
How Do I Choose the Right Auxiliary Fuel Tank Pump Kit?
Selecting the appropriate kit requires careful consideration of several factors:
- Vehicle Compatibility: Ensure the kit is compatible with your specific vehicle's make, model, and year. Pay close attention to fuel system requirements and pressure ratings.
- Tank Capacity: Choose a pump with sufficient flow rate for your auxiliary tank's size.
- Pump Type (Electric or Mechanical): Consider the ease of installation, control preferences, and vehicle's electrical system capacity.
- Kit Components: Review the included components to ensure everything necessary for a complete installation is provided.
What are the Potential Issues with Auxiliary Fuel Tank Pump Kits?
While generally reliable, potential problems include:
- Pump Failure: Like any mechanical or electrical component, pumps can fail, potentially leaving you stranded.
- Leaks: Improper installation or damaged tubing can lead to fuel leaks.
- Electrical Issues (Electric Pumps): Wiring problems or short circuits can occur.
How Difficult is it to Install an Auxiliary Fuel Tank Pump Kit?
The installation difficulty varies depending on the kit and vehicle. Some kits are relatively straightforward to install, while others may require more mechanical aptitude or professional assistance. Always consult the kit's installation instructions carefully.
Where Can I Buy an Auxiliary Fuel Tank Pump Kit?
Auxiliary fuel tank pump kits are available from various retailers, including online marketplaces and automotive parts stores. It's crucial to research different brands and compare features and prices before making a purchase. Reading customer reviews can also help in selecting a reliable and well-regarded kit.
This guide provides a starting point for understanding auxiliary fuel tank pump kits. Always consult a professional if you are unsure about any aspect of installation or have concerns about your vehicle's fuel system. Remember to prioritize safety and follow all manufacturer instructions carefully.
