A hanger for hanging a fluid reservoir relative to an endoscope cart, the hanger comprising:

• a body portion defining a central opening;
• a plurality of coupling mechanisms extending through a wall of the body portion, the plurality of coupling mechanisms movable between a radially extended and a radially contracted configuration;
• and
• a hook secured to the body portion.

A hanger for hanging a fluid reservoir relative to an endoscope cart, the hanger comprising:

• a generally “U” shaped body portion having a first leg including first adjustment mechanism, a second leg including a second adjustment mechanism, and a third leg, the second leg extending generally orthogonal to and between the first leg and the third leg;
• and
• a curved hook portion extending from the third leg;
• wherein a portion of the first leg is configured to engage a ledge of a shelf of an endoscope cart.
