To keep oil liquified we run this line with our fuel line:

A tracer line is used in conjunction with a fuel line to maintain oil in a liquefied state. This method typically involves running warm fluid through the tracer line, which assists in preventing the oil from solidifying or thickening, especially in colder temperatures. The heated fluid in the tracer line transfers heat to the surrounding oil line, ensuring that the fuel remains in a workable, liquid form. This is particularly important in systems where oil viscosity can dramatically affect performance and flow, such as in heating systems or machinery where oil is used as a lubricant. The tracer line's purpose is critical in enhancing the efficiency and reliability of fuel delivery and overall plant operations.
