Building a fuel tank stand can be a challenging endeavour. Before you start, it is important to consider the design, materials, and any relevant regulations. Many localities have outlawed fuel stands due to the risk of valve or hose failure, which can result in a large amount of fuel being spilled. It is also crucial to determine the size and placement of the fuel tank, ensuring it is not located near the exhaust or in an area where it could be damaged. When it comes to materials, options include wood, steel, and fiberglass, each with its own advantages and disadvantages. For example, wood is a traditional choice but may require longer posts and cross-bracing to ensure stability. Steel is strong but can be prone to corrosion, while fiberglass offers flexibility in design but may require additional sealing to prevent leaks.

What You'll Learn
Selecting the right materials
Durability and Corrosion Resistance:
Choose materials that can withstand the elements and the weight of the fuel tank. Stainless steel, for instance, is highly resistant to corrosion and is a suitable option for welding a fuel tank together. While mild steel is more affordable, it requires coating both the inside and outside to prevent corrosion, which can be tedious and may not hold up over time.
Weight and Stability:
Consider the weight of the fuel and the stability of the stand. Track cars, for instance, can be affected by the shifting weight of fuel, impacting the balance of the vehicle. Ensure that the materials used for the stand can bear the weight of the fuel tank and that the design includes measures to prevent the tank from rolling off, such as cross braces.
Environmental Factors:
Take into account the environmental conditions where the fuel tank stand will be placed. Ensure that the materials used can withstand exposure to the elements, such as rain or extreme temperatures. Additionally, be mindful of any local laws or regulations regarding fuel tanks. Some localities have outlawed certain types of fuel stands due to environmental concerns.
Functionality and Compatibility:
Select materials that are compatible with the fuel type. For example, consider using fiberglass to build a custom fuel tank, especially if you plan to use ethanol-tainted fuel. Coatings like KBS Gold Standard have been reviewed positively for their compatibility with fiberglass and their ability to prevent leaks.
Prototyping and Testing:
Before committing to expensive materials, create a prototype to test the design and fit. Cardboard is an excellent material for prototyping, allowing you to make adjustments before final fabrication. Once you're satisfied with the prototype, select materials that align with your design and are suitable for the fuel type and environmental conditions.

Design and measurements
The first step in designing a fuel tank stand is to take accurate measurements of the space where the stand will be placed. This includes considering the size of the fuel tank itself, as well as any additional components such as fuel pick-ups, vents, fuel fillers, mounting straps, fuel level sensors, and fuel lines. It is also important to ensure that the fuel tank is located in an area that will not be exposed to excessive heat, or plan to build heat shielding if necessary.
When it comes to the stand's design, it is recommended to start by drawing out your plans on paper. This allows you to visualize the stand's dimensions and make any necessary adjustments before beginning construction. Consider the weight of the fuel tank and select an appropriate material for the stand that can bear this load. Wood and steel are commonly used materials for fuel tank stands.
If you're using wood, old wooden stands typically consisted of four longer-than-normal posts (8 to 10 feet) with a cross brace to support the tank. The cross brace is usually 6 to 8 inches lower than the top of the posts to prevent the tank from rolling off. It is recommended to bolt the crossbars for added security. Setting the posts 2 feet into the ground can provide stability, and some people choose to enclose the sides to create a small storage space for oil or other items.
For steel stands, you can use mild steel or stainless steel. Mild steel is more affordable but requires coating on both the inside and outside to prevent corrosion. Stainless steel is more resistant to corrosion and is easier to weld but may be more expensive. Regardless of the material, it is important to consider the thickness of the metal, with 10-gauge or 12-gauge steel being commonly recommended for strength and durability.
Before beginning construction, it is beneficial to create a prototype or mock-up of your design to ensure it fits properly and functions as intended. Cardboard or other inexpensive materials can be used for this purpose, allowing you to make any necessary adjustments before committing to the final build.

Building a prototype
Before building a prototype of your fuel tank stand, it is important to take measurements of the space where you plan to place it. This includes considering the size of the fuel tank and ensuring that there is space for fuel pick-ups, vents, fuel filler, mounting straps, fuel level sensors, and fuel lines. Additionally, you should determine whether the tank will be placed in an area exposed to high temperatures, such as near an exhaust, and plan to build heat shielding if necessary.
Once you have your design on paper, the next step is to create a prototype. Cardboard is an excellent material for this purpose. Take your measurements and construct a cardboard model of the fuel tank stand, ensuring that the cardboard pieces represent the actual components you will use in the final build. This step allows you to test the fit and make any necessary modifications before investing in more expensive materials.
When selecting materials for your prototype, consider the advantages and disadvantages of different options. For example, mild steel is corrosive, so it requires a coating on both the inside and outside, which can be tedious and may not hold up over time. Stainless steel, on the other hand, is highly resistant to corrosion and relatively easy to weld, making it a more durable and cost-effective choice.
Another option for your prototype is to use fiberglass. While it offers customization and cost-effectiveness, selecting the appropriate resin and ensuring proper sealing are critical to the success of a fiberglass fuel tank. Research and consult reliable sources and reviews to guide your decision-making.
Lastly, consider the functionality of your prototype. For example, if you are building a large fuel tank, you may want to incorporate a method to divide it into smaller sections. This design approach prevents fuel sloshing, ensuring that the fuel pump pickup remains submerged and minimizing weight shifts that can affect balance.

Construction
Constructing a fuel tank stand requires careful planning and execution to ensure safety and functionality. Here is a step-by-step construction guide:
Planning and Design:
Start by taking precise measurements of the space where the fuel tank stand will be placed. Consider the size of the fuel tank, including its height, width, and depth. Ensure there is adequate clearance for fuel pick-ups, vents, fuel filler, mounting straps, fuel level sensors, and fuel lines. Additionally, determine the weight of the fuel tank when full and design the stand to safely support that weight.
Materials:
The choice of materials for the stand depends on factors such as durability, corrosion resistance, and cost. Wooden stands were commonly used in the past, with longer posts (8 to 10 feet) set in the ground for stability. However, wood is susceptible to rotting over time. Metal, particularly stainless steel, is a more durable option. Stainless steel is highly resistant to corrosion and relatively easy to weld. If using wood, consider pressure-treated lumber to improve durability.
For a wooden stand, set four vertical posts 2 feet into the ground, spaced to fit the dimensions of your fuel tank. Ensure the posts are level and securely anchored. Create a cross brace near the top of the posts to support the fuel tank and prevent it from rolling off. Bolt the cross braces together for added strength. You may also enclose the sides to create a small storage area underneath the tank.
For a metal stand, welding is typically required. Cut and assemble metal sheets or plates according to your design, ensuring precise measurements. Weld the seams and joints securely, and consider adding baffles or reinforcing plates for additional strength. If using stainless steel, you can avoid the need for coatings, unlike mild steel, which requires both the interior and exterior to be coated to prevent corrosion.
Final Steps:
Once the stand is constructed, carefully place the fuel tank on top, ensuring it is secure and stable. Drill holes in the tank for valves, fuel filler, and any other necessary components. Install these components, following manufacturer instructions and industry safety standards.
Remember to comply with local regulations and guidelines regarding fuel storage. It is essential to prioritize safety throughout the construction process to mitigate the risk of fuel leaks or structural failures.

Testing
When building a fuel tank stand, there are several aspects to consider when it comes to testing. Firstly, it is important to ensure that the stand can securely hold the fuel tank in place. This can be tested by mounting the fuel tank onto the stand and checking if it is stable and does not move or wobble. It is crucial to use the appropriate mounting hardware and to ensure that the fuel tank is securely fastened to the stand.
Another aspect to test is the ease of refuelling and cleaning. The fuel tank stand should be designed in a way that allows for easy access to the fuel tank cap or opening. This can be tested by simulating the refuelling process and ensuring that it can be done safely and efficiently. Additionally, the stand should be designed to minimise fuel spillage and facilitate easy cleaning in case of any spills or leaks.
The fuel tank stand should also be tested for its ability to withstand the weight of the fuel tank when it is full. This can be done by filling the fuel tank to its maximum capacity and observing the stability of the stand. It is important to ensure that the stand can bear the weight without any signs of strain or instability.
Furthermore, if the fuel tank stand is intended to be portable, its mobility should be tested. This includes checking the ease of moving the stand, its stability during transportation, and its ability to be securely positioned in the desired location.

Frequently asked questions
You can use wood, steel, or fiberglass to build a fuel tank stand.
Wood is a good option if you want to build a tall stand. However, you should be aware that many localities have outlawed wooden fuel stands because they gravity feed, meaning that if there is a failure of the valve or hose, all the contents will drain out.
Stainless steel is highly resistant to corrosion and not terribly difficult to weld, but it is more expensive than mild steel. Mild steel is corrosive, so you will need to coat the inside and outside of the tank, which can be tedious and may not hold up well over time.
Fiberglass is a cheaper option, but it may not be as durable as steel or wood. You will need to use a resin to seal the tank and prevent leaks.
