What must be ensured when using a fuel oil line?

When working with a fuel oil line, it is essential to ensure that the static pressure does not exceed a specific threshold. This is crucial because excessive static pressure can lead to leaks, potential spills, or even catastrophic failures in the system. Maintaining the pressure within allowable limits helps ensure the safe operation of the fuel system, as it prevents undue stress on the components and reduces the risk of fire hazards associated with fuel oil.

In many cases, fuel oil systems are designed to operate under controlled pressure conditions, which may be specified by industry standards or manufacturer guidelines. Adhering to these thresholds not only preserves the integrity of the fuel line but also ensures compliance with safety regulations.

The other options, while potentially relevant to the operation of fuel systems, do not directly address the critical aspect of maintaining static pressure within a safe range. This highlights the central importance of ensuring that static pressure thresholds are not exceeded in the context of fuel oil lines.
