What is the best material for a fuel tank?

--

Introduction

The fuel tank of your car is a very important component, and selecting the right one can be challenging. There are several types of materials that can be used for fuel storage tanks and each has its own advantages and disadvantages. In this article we’ll discuss what factors you should take into consideration when choosing the best material for your tank.

Types of fuel storage tanks

• Metal
• Plastic
• Composite, which is an engineered material made of polymer and resin
• Rubber. The advantages of rubber include it’s elasticity and durability, but it can have a high tendency to leak because of its flexibility. It also requires special venting to prevent air pockets in the tank and the gas from coming into contact with oxygen in order to prevent explosions.
• Glass-fiber reinforced plastic (GRP). This kind of composite has excellent mechanical properties at low temperatures, which makes it ideal for use as a fuel tank on boats or submarines.

Corrosion in different materials

Steel is the most common material used in fuel tanks. It’s strong, flexible and cheap. However, steel is vulnerable to corrosion if it’s not coated with a protective layer.

The most common coating for steel is polyurethane foam (PUF). The PUF coating creates an inert gas barrier between the tank and its contents that prevents degradation by reducing contact between them while also preventing rusting and corrosion of the tank itself through oxidation prevention (inhibiting rust from forming on metal surfaces). Packed foods are considered high-oxygen content items because they contain water which can promote oxidation reactions when exposed to air at room temperature over time; therefore this type of storage container should never be used for any food product unless it has been treated against such hazards — which would include using one made out of stainless steel!

Which material is best?

The most common material for fuel tanks is steel. It’s cheap and easy to work with, and it lasts a long time.

Metal fuel tanks are much more expensive than plastic ones, but they also last longer. They tend to be heavier than plastic tanks but are more durable as a result (and sometimes lighter).

There are 4 common materials used for fuel tank construction and each has its own advantages and disadvantages

There are four common materials used for fuel tank construction and each has its own advantages and disadvantages. They are:

• Aluminum — Cheaper than other materials, lighter than steel.
• Steel — More durable than aluminum and stainless steel, but heavier.
• Stainless Steel — Stronger than aluminum and lighter than carbon fiber.
• Carbon Fiber — The strongest of all the materials, but also the most expensive.

Conclusion

We hope this article has helped you to better understand the different types of tanks and materials used in their construction. The main takeaway here is that there’s no clear winner when it comes to which material is best for fuel storage tanks. Each type has its own advantages and disadvantages, but all of them will work well if they are properly designed and built by an experienced company like ours!

A fuel transfer tank can be mounted in the bed of a pickup truck to serve as an external source of gasoline or diesel. These tanks require a transfer pump to move fuel into the vehicle’s factory tank, but since they can be used anywhere and at any time, they’re often more convenient than stopping at a traditional gas station.

A fuel transfer tank can be invaluable in situations such as:

• Working in remote areas with limited access to fuel
• Traveling long distances
• Managing time-sensitive tasks
• Increasing the range of a smaller accompanying vehicle
• Refueling equipment like generators
• Responding to emergencies or natural disasters
• Purchasing more fuel in a cheaper area to save money

Benefits of Owning a Fuel Transfer Tank

Owning a fuel transfer tank provides several advantages beyond convenience and flexibility: 

• Cost Savings: Purchasing fuel in bulk or in regions with lower prices can lead to significant cost savings over time.

• Increased Productivity: By minimizing downtime spent refueling, a fuel transfer tank can help increase productivity for individuals and businesses involved in construction, agriculture, or other industries requiring heavy equipment.

• Emergency Preparedness: Fuel transfer tanks can serve as a valuable resource during emergencies or natural disasters when access to fuel may be limited.

• Versatility: The ability to transport multiple types of fuel, including gasoline, diesel, kerosene, ethanol, methanol, and aviation fuel, allows for a wide range of applications and uses.

• Customization: Many tank brands offer custom options and upgrades to meet specific needs or preferences, such as additional storage compartments or specialty finishes.

How to Measure your Pickup Truck Bed Space for a Fuel Transfer Tank

Measuring a transfer tank to fit your truck bed involves taking accurate measurements of your truck bed and comparing them to the dimensions of the transfer tank you are considering installing in your truck.

Review the dimensions of the transfer tank you are considering, including its length, width, height, and shape. Compare these dimensions to your truck bed measurements to ensure compatibility.

Be aware of any additional space needed for mounting hardware, fuel transfer equipment, and clearance around wheel wells or other obstructions. 

Length

Measure the length of your truck bed from the bulkhead (front) to the tailgate (rear). If your truck has wheel wells, measure the length of the bed in front of and behind the wheel wells.

Width

Measure the width of your truck bed from one side to the other, both at the narrowest point (between the wheel wells) and at the widest point (the bed rails).

Height

Measure the height from the bed floor to the top of the bed rails. If you plan to use a tonneau cover or have other height restrictions, take note of the maximum allowable height for a transfer tank.

Transfer Tank Material: Aluminum vs Steel

Aluminum and steel are the two most common materials used in the construction of fuel transfer tanks. Each material has its advantages and disadvantages, which can impact the overall performance, durability, and cost of the transfer tank.

Aluminum Transfer Tanks

Pros

• Lightweight: Aluminum transfer tanks are generally lighter than their steel counterparts. This reduces the overall weight added to the vehicle, which can be beneficial for fuel economy and payload capacity.

• Corrosion Resistance: Aluminum is naturally resistant to rust and corrosion, making it an excellent choice for outdoor use and in areas with high moisture or salt exposure. This resistance can lead to a longer lifespan for the transfer tank.

• Heat Dissipation: Aluminum dissipates heat more effectively than steel, which can help maintain a consistent temperature within the transfer tank and reduce the risk of fuel overheating or expanding.

Cons

• Lower Strength: Aluminum transfer tanks are generally not as strong as steel tanks, making them more susceptible to dents and damage from impacts.

Steel Transfer Tanks

Pros

• Strength and Durability: Steel transfer tanks are typically stronger and more durable than aluminum tanks. This makes them more resistant to dents, punctures, and other damage, which can be beneficial in heavy-duty applications or harsh environments.

Cons

• Weight: Steel transfer tanks are usually heavier than aluminum tanks, which can impact fuel economy and reduce the payload capacity of the vehicle.

• Corrosion: Steel is more susceptible to rust and corrosion than aluminum, particularly in damp or salty environments. This susceptibility can reduce the lifespan of the transfer tank and may require additional maintenance or protective coatings to prevent corrosion.

We sell steel tanks which include a standard black powder coat finish that prevent corrosion and provide a nice sleek finish. 

When choosing between aluminum and steel transfer tanks, it is essential to consider factors such as weight, strength, corrosion resistance, and cost. Aluminum transfer tanks are lightweight and corrosion-resistant but can be less durable.

In contrast, steel transfer tanks offer strength and durability but can be heavier and more prone to corrosion.

Transfer Tank Fuel Capacity

Make sure to consider what the right amount of extra fuel capacity is for your pickup truck. Remember that larger tanks will take up more space in your truck bed, and the weight of a full tank can affect your fuel economy.

Fuel transfer tanks can hold anywhere from 20 to over 100 gallons. Smaller models may feature a slimmer profile to conserve bed space by increasing height. Some tanks can be as tall as 27 inches, with the top extending above the bed rails.
