What is located between the supply tank and the pump in an oil delivery system?

In an oil delivery system, a fuel line filter is positioned between the supply tank and the pump to ensure that the oil being delivered to the burner is clean and free from impurities. The filter plays a crucial role in maintaining the efficiency and reliability of the oil burner by trapping dirt, debris, and other contaminants that can clog the oil line or damage the burner components.

If contaminants were to reach the pump or the burner itself, they could hinder performance, cause mechanical failure, or lead to inefficient combustion. Thus, the fuel line filter is an essential component that helps to protect the entire system from potential issues associated with unfiltered oil. Proper maintenance of the fuel filter is also necessary to ensure that it functions effectively and does not become clogged, which could restrict oil flow and affect burner operation.
