Where shall supply piping connect to a fuel oil tank?

Connecting the supply piping to the top of the fuel oil tank is important for several reasons related to the proper functioning and safety of the system. When the supply piping is connected at the top, it allows for effective extraction of the fuel, ensuring that the tank can be drained properly. This connection helps prevent the risk of siphoning, which can occur if the supply line is connected to the bottom, especially in situations where the tank is not full.

Additionally, connecting to the top of the tank minimizes the chance of drawing sediment or sludge that can accumulate at the bottom of the tank, which can lead to clogs and damage in the fuel delivery system. This practice also aligns with industry standards and codes designed to promote safe and efficient operation of fuel oil systems.

In some cases, supply piping may be required to connect at specific points on the tank, and the top connection typically fulfills these safety and operational standards effectively.
