What are the two main methods of filling an oil tank?

1. Pump filling and vapor recovery

2. Suction filling and gravity feed

3. Gravity feed and pump filling

4. Direct filling and indirect filling

The correct answer is: Gravity feed and pump filling

The two main methods of filling an oil tank are gravity feed and pump filling. Gravity feed relies on the natural force of gravity to transfer the oil from the delivery truck or container directly into the tank. This method is simple and effective, especially for lower tanks, as it does not require any mechanical assistance to move the oil. Pump filling, on the other hand, utilizes a mechanical pump to transfer the oil into the tank. This method is often used for tanks that are situated at a higher elevation or where gravity feed would be insufficient. Pumps are essential for ensuring that the oil is delivered quickly and efficiently, particularly in residential or commercial settings where large volumes of oil need to be managed. Both methods are widely utilized in the industry depending on the specific circumstances of the installation and the physical layout of the site. Understanding these methods is crucial for safe and effective oil tank filling procedures.
