Adding an auxiliary fuel tank significantly extends your vehicle's range, proving invaluable for long-distance travel, off-road adventures, or situations where fuel stations are scarce. 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 essential kits, helping you choose the right one for your needs.
What is an Auxiliary Fuel Tank Pump Kit?
An auxiliary fuel tank pump kit is a collection of components designed to draw fuel from your secondary tank and deliver it to your vehicle's main fuel system. Typically, the kit includes:
- Electric Fuel Pump: The heart of the system, responsible for transferring fuel. Different pumps offer varying flow rates and pressure capabilities, crucial considerations based on your vehicle and tank size.
- Wiring Harness: Provides power to the pump, often including a switch for convenient on/off control and potentially an in-line fuse for safety.
- Tubing and Fittings: Connects the pump to the auxiliary tank and the main fuel system, ensuring a leak-free and secure fuel transfer. Materials like high-pressure fuel-resistant hose are crucial for safety and longevity.
- Filter: Prevents debris from entering your main fuel system, protecting your engine's delicate components.
- Mounting Brackets and Hardware: Securely fasten the pump and related components to the auxiliary tank or vehicle frame.
Choosing the right kit requires careful consideration of factors discussed below.
What are the Different Types of Auxiliary Fuel Tank Pump Kits?
Auxiliary fuel tank pump kits vary based on several factors:
- Pump Type: Electric pumps are the most common due to their ease of installation and operation. However, some systems might incorporate a gravity-fed system, relying on the tank's elevation to move fuel, although less efficient and potentially problematic in certain situations.
- Flow Rate: This determines how quickly fuel is transferred. Higher flow rates are preferable for quicker refueling, but require a more powerful pump.
- Pressure: Adequate pressure is crucial to ensure fuel reaches the engine efficiently. Kits must be matched to your vehicle's fuel system requirements.
- Material: Durable and fuel-resistant materials are essential. Avoid kits with components that could degrade or leach chemicals into your fuel.
How Do I Choose the Right Auxiliary Fuel Tank Pump Kit?
Selecting the appropriate kit depends on several key factors:
- Vehicle Compatibility: The pump's flow rate and pressure must match your vehicle's fuel system specifications. Incorrectly matching components can lead to poor performance or even damage to your engine.
- Tank Size: Larger tanks generally require higher-flow-rate pumps for efficient refueling.
- Fuel Type: Ensure the kit is compatible with your vehicle's fuel type (gasoline, diesel, etc.).
- Installation Location: The pump's size and mounting requirements should be considered in relation to available space in or near your auxiliary tank.
What are the potential problems with Auxiliary Fuel Tank Pump Kits?
While offering substantial benefits, auxiliary fuel tank pump kits can present some potential challenges:
- Leaks: Improper installation or damaged components can lead to fuel leaks, posing a serious safety hazard.
- Pump Failure: Like any mechanical component, pumps can fail. Choosing a reputable brand and performing regular maintenance can help mitigate this risk.
- Wiring Issues: Faulty wiring can lead to power loss or electrical shorts.
- Compatibility Issues: Incorrectly matched components can negatively impact performance and potentially damage your vehicle.
How do I install an Auxiliary Fuel Tank Pump Kit?
Installation complexity varies greatly depending on the kit and vehicle. Some kits offer straightforward installation, while others require more advanced mechanical knowledge. Always consult the kit's installation instructions and, if needed, seek professional help. Safety should be the top priority; improper installation can lead to significant problems.
What maintenance does an auxiliary fuel tank pump kit require?
Regular maintenance extends the life of your pump kit and minimizes the risk of failure:
- Check for leaks regularly.
- Inspect wiring and connections for any damage or corrosion.
- Replace the fuel filter as recommended by the manufacturer.
- Consider a yearly professional inspection if you lack mechanical expertise.
By carefully considering these factors and following proper installation and maintenance procedures, you can enjoy the extended range and increased capability offered by an auxiliary fuel tank and its pump kit. Remember, safety should always be your top priority.
