Locate the fuel line: The fuel line is the pipe that carries fuel from the oil tank to the furnace. It is usually made of copper or plastic and is located near the bottom of the furnace.
Disconnect the fuel line: Use a wrench to disconnect the fuel line from the furnace and the oil tank. Be careful not to spill any fuel.
Clean the fuel line: Use a wire brush or a pipe cleaner to clean the inside of the fuel line. Remove any dirt, debris, or rust that may be blocking the flow of fuel.
Flush the fuel line: Use a garden hose to flush the fuel line with water. This will help to remove any remaining debris and ensure that the fuel line is clear.
Reconnect the fuel line: Once the fuel line is clean, reconnect it to the furnace and the oil tank. Be sure to tighten the connections securely.
Prime the fuel line: Before you turn on the furnace, you need to prime the fuel line. This means filling the fuel line with oil. To do this, open the valve on the oil tank and let the fuel flow into the fuel line. Once the fuel line is full, close the valve.
Turn on the furnace: Once the fuel line is primed, you can turn on the furnace. The furnace should start up and run normally.
If you are still having problems with your furnace after following these steps, you should contact a qualified heating technician for assistance.
