1. A no emission tank gauge system, comprising:
a housing having a valve connection extending from a bottom side of the housing;
a gauge line within the housing, the gauge line having a plumb bob attached at a free end; a gauge liquid remover;
a pulley attached within the housing and supporting the gauge line, the pulley configured to allow extension and retraction of the gauge line; and
an actuator connected to the pulley and extending exterior to the housing and configured to actuate the extension and retraction of the gauge line via rotation of the pulley, wherein:
the housing has a window in a wall of the housing facing a marked side of the gauge line;
the valve connection has an opening sized to allow for passage of the plumb bob and the gauge line; and
the housing is sealed when the valve connection is connected to a valve to prevent escape of fluid wherein the gauge line liquid remover comprises: a cleaning member attached within the housing such that a surface of the cleaning member aligns with a first side of an opening of the valve connection; and a plunger movably attached within the housing and having a first end positioned external to the housing and a second end within the housing, wherein: the plunger has a first position in which the second end is not within a circumference of the opening of the valve connection and a second position in which the second end is within the circumference of the opening of the valve connection, and the plunger is configured to be manually moved between the first position and the second position via the first end.
