Oil Tank Lines

The old line is exposed and kinked a bit, so I will replace that. So by having just a single line, the boiler will not become loaded with unused fuel? Does the burner actually have suction with a single line setup or is it fed by gravity?

    I am in the process of converting my home heating from forced hot air to baseboard. My previous furnace was lower in height had a single feed line from the oil tank, which is about 5 feet away.

    My new burner (Beckett) is about 8 inches above the bottom of the oil tank level. The installation manual says a 2 line system is required if the burner is at or above the supply.

    How do I convert my tank to two lines? Where does the return line return to?

    Any input would be appreciated. Thanks.

    No need to change

    Leave the system set up as one line, no need to change to two pipe. How old is original oil line? If not exposed but buried in the floor it would be a good time to replace if it has been there for some time.

    The pump will develop suffucient vacuum for that tiny lift.

    And it will be gravity if the level of fuel is above the level of the burner.

    As far as the boiler loading up with fuel, the pump cut off will prevent that. Adn the pump cut off should be tested annually.
