Whether you’re purchasing your first above ground storage tank or planning a complex fueling system, having accurate information is essential. For that reason, our fuel storage resources bring together practical guides, industry knowledge, and educational information to help you make informed decisions.
Search our Resource Library for articles, guides, regulations, tank types, equipment, and industry-specific information.

Whether you’re purchasing your first above ground storage tank or planning a complex fueling system, understanding your options can make the process easier. From UL 142 tanks and Fireguard® tanks to fueling systems, regulations, maintenance, and accessories, our above ground storage tank resources bring helpful information together in one place. You can also explore official guidance from UL, Steel Tank Institute (STI/SPFA), and NFPA for additional information about industry standards and fuel storage requirements.
In addition, you can explore information about tank construction, equipment, applications, regulations, and project planning. For example, the EPA provides resources covering oil spill prevention and SPCC requirements. As a result, you can spend less time searching for answers and more time planning the right storage solution for your operation.
Explore our collection of guides, articles, and technical resources organized by topic. Whether you’re researching a specific tank or planning an entire fuel storage system, choose a category below to find information that fits your project.
First, learn the fundamentals of above ground storage tanks, fuel storage systems, secondary containment, and common tank types.
Next, plan your project with guidance on tank sizing, specifications, site planning, installation considerations, and equipment selection.
Compare tank types, features, applications, and industry standards before choosing a storage solution. For example, our guides explain the differences between different tank designs.
Learn about installation, inspections, repairs, refurbishment, fabrication, and other tank services. In addition, these resources explain how proper service and maintenance can support long-term tank reliability.
Explore pumps, gauges, overfill prevention, monitoring systems, filtration, dispensing equipment, and other tank accessories. Whether you need a basic pump package or a complete fueling system, these resources can help you understand your options.
See how fuel storage systems support farms, construction companies, mining operations, aviation facilities, fleets, municipalities, and other industries. Because every operation has different requirements, these guides focus on solutions for specific applications.
Learn about storing diesel, gasoline, DEF, waste oil, chemicals, water, aviation fuels, and other compatible liquids. Depending on the stored product, equipment requirements may vary.
Learn how inspections, maintenance, repairs, and refurbishment can help extend the life of your storage system. In addition, explore information about identifying problems before they become expensive repairs.
Finally, access tank inches-to-gallons tank strapping charts, capacity tables, dimensions, and other technical reference information to help plan your project.
Above ground storage tanks support operations across agriculture, construction, manufacturing, municipalities, aviation, mining, emergency power, and many other industries. However, choosing the right tank involves more than selecting a capacity. Fuel type, local requirements, site conditions, dispensing needs, and future growth can all influence the right solution.
For that reason, our fuel storage resources were created to simplify the research process. Whether you’re researching your first tank or planning a complex fueling system, you’ll find practical information written in plain language. As a result, you can better understand your options before making important project decisions.
For example, some projects may only require a standard UL 142 tank. Meanwhile, other installations may call for additional secondary containment or fire protection. Our guides help explain those differences so you can ask better questions and work with your local Authority Having Jurisdiction (AHJ), engineer, or other project professionals when needed.
If you’re new to above ground storage tanks or simply looking for reliable information, these guides are a good place to begin. First, they answer some of the most common questions we hear from customers. Then, you can explore more specialized topics as your project develops.

Compare common tank designs and learn how capacity, secondary containment, fire protection, site conditions, and equipment requirements can influence your decision.
Then, compare Flameshield® tanks with standard UL 142 and protected-tank options while learning where this design fits your project.

If you’re comparing protected and standard above ground storage tanks, learn how UL 2085 and UL 142 differ in construction, protection, and common applications.

Finally, learn about common regulations, codes, permitting considerations, and the role of the Authority Having Jurisdiction when planning an installation.
Every fuel storage project is different. Therefore, asking the right questions early can save time, reduce unexpected costs, and help you choose the right equipment.
Before purchasing an above ground storage tank, consider:
If you don’t know every answer yet, that’s okay. For example, your local fire marshal or other AHJ can help identify requirements that apply to your installation. Then, our team can help you understand the tank configurations and equipment options available for your project.
For additional planning information, explore our How to Specify UL Tanks, Fuel Tank Codes, and Tank Optionsresources.
For more than three decades, Clark Welding Tanks has helped customers select, build, and support above ground storage tanks for a wide range of industries. Because every project is different, we believe customers should understand their options before choosing a tank.
For that reason, we created this Fuel Storage Resource Library to share practical guides, technical references, and straightforward information based on the questions customers ask us every day. Whether you’re comparing tank types, researching regulations, selecting equipment, or planning your next project, our goal is simple: provide useful information that helps you make an informed decision.
In addition, we continue adding resources as new questions and topics arise. If you cannot find the information you need, contact our team and we’ll be happy to help point you in the right direction.
Whether you’re planning a single storage tank or a complete fueling system, Clark Welding Tanks is here to help. First, tell us what you’re storing, how much capacity you need, and how you plan to use the system.
Then, we’ll help you understand the tank construction, equipment, and options available for your application. Finally, contact our team to discuss your project or request a quote when you’re ready to move forward.
