    "blow back line" refers to a mechanical device.

    blowback - the escape to the rear of gases formed during the firing of a weapon or in a boiler, internal-combustion engine, etc
    line - 7. A pipe or system of pipes for conveying a fluid

    So it would be translated to something like "linha de retorno de gás" or "linha de descarga de gás"
