What You'll Learn
Fuel tank maintenance
Firstly, it is important to consider the type of tank you have and whether it falls under the API 653, STI SP001, or API 510 standards. These standards will determine how often your tank needs to be inspected. For instance, the API 653 standard applies to aboveground storage tanks that are field-erected or field-built, made of steel or other metal alloys, and have a diameter of 30 feet or more, or a height of 50 feet or more. Tanks that fit within this standard should separate internal and external inspections. The frequency of internal inspections depends on factors such as the tank's size, age, and the materials it stores. A tank's first internal inspection should take place 10 years after the construction date, and then every 20 years thereafter. External inspections should be conducted at least once every five years, but more frequent inspections may be necessary depending on the age of the tank and operating conditions.
Aboveground storage tanks (ASTs) are a popular bulk fuel storage solution. They are easier to maintain and relocate, safer for the environment, and subject to fewer federal regulations than underground storage tanks. Underground leaks are difficult to detect and expensive to clean, and they are more likely to affect freshwater and become an environmental disaster. ASTs should be placed in an east-west orientation to reduce exposure to solar radiation, which can cause fuel tank weathering and lead to a brittle tank. Proper maintenance can reduce weathering effects, as can a roof or covering. ASTs should also be fire-guarded or vaulted in case of an emergency.
To maintain your fuel tank, it is important to keep the area around it clear of debris and vegetation so that any drips and spills can be easily identified. A weekly check for water or product in the interstitial space (containment area) should be carried out, and any rainwater and diesel should be removed. Vents and valves should be inspected to maintain fuel flow, and filler caps should be removed and cleaned with a wire brush if necessary. Hinges should be lubricated to avoid rust and wear and tear, and a small amount of lithium grease should be applied to vents and valves to prevent rust buildup. Fuel inspections should take place regularly, with some parts needing to be checked more often than others. Vents, fittings, and pipelines require a visual check every week for signs of leaks or damage, and a physical check for bolt tightness, paint deterioration, and the general condition of pumps, vents, and valves should be conducted every six months.
Finally, it is important to check the quality of your fuel. Using poor-quality fuel can damage both your tank and equipment, leading to costly fixes.

Fuel dispenser inspection frequency
API 653, for instance, applies to aboveground storage tanks made of steel or metal alloys with specific dimensions, typically used for hazardous materials. According to this standard, the first internal inspection occurs 10 years after construction, followed by inspections every 20 years, unless concerns are identified earlier. External inspections are recommended at least once every five years, but age, operating conditions, and previous findings may require more frequent checks.
For fuel systems in vehicles, inspection frequencies vary for different components. Fuel filters, for instance, typically need inspection and replacement every 10,000 to 15,000 miles, while fuel injectors should be inspected annually. Fuel pumps should be inspected every 60,000 miles to detect signs of wear or malfunction, though some sources suggest doing so whenever the car is professionally serviced. Regular check-ups for the entire fuel system are recommended every 10,000 to 15,000 miles or at least annually.
In general, fuel tank maintenance involves routine visual inspections to identify leaks, drips, and spills. This is recommended at least weekly, with some suggesting checks every six to twelve months. Water and biological contaminants are particularly important to identify, as they can lead to engine failure and reduced tank lifespan. Fuel sampling and integrity testing are also recommended annually, with more frequent inspections during harsh winters or when fuel remains in the tank for extended periods.

Fuel pump inspection
Frequency of Inspection
It is recommended to inspect the fuel pump every 60,000 miles or at least once a year. Regular check-ups are advised every 10,000 to 15,000 miles as a proactive approach to maintaining the fuel system. However, if there are any signs of malfunction or unusual performance, the fuel pump should be inspected regardless of the mileage.
Visual Inspection
Before commencing any inspection, ensure the vehicle is parked in a clear area, away from potential safety hazards. Look out for any signs of fuel leaks or spills around the fuel tank and pump. Keep the area free from debris and vegetation to easily identify any drips or spills.
Operational Test
If the vehicle is equipped with a fuel level sensor, ensure it is functioning correctly by monitoring the fuel gauge. A properly functioning fuel level sensor provides accurate information about the amount of fuel in the tank.
Fuel Pump Functionality
The fuel pump plays a critical role in delivering fuel from the tank to the engine. Inspect the fuel pump for any signs of wear, malfunction, or damage. Surging fuel towards the engine or insufficient fuel delivery indicates the need for inspection and possible repair or replacement.
