I recently installed a GO-5 beckett oil burner/new boiler but the system existing has a 2 pipe line. I hooked the existing bypass oil line but without the plug. (I do mostly gas).
What is the ramifications of not installing the bypass plug. Its only been 1 day since install. I have the plug now in hand.

    The burner may not be able to pump the oil. This problem may not show up right away however.

    If that were my job, and the usual single-line hookup would not work, I'd use a TigerLoop to eliminate the return line. Return lines run under some pressure, and can cause much environmental damage if they leak.

    You would need the bypass plug to make the TigerLoop work.

    Are you sure you need two pipe?
    If it’s the same model fuel pump as the one you took out, you could reuse the plug from that one.

    Note to anyone who stumbles onto this thread.
    If you did it the other way, put in a bypass plug and switched it to one pipe oil line, you would almost instantly destroy the fuel pump.
