The present disclosure relates to the construction and use of feedlines in temperature-biased systems that include counter-biased hoses. The alignment and installation/uninstallation of the counter-biased hoses is enabled by a biasing tool with at least a first yoke having a first rotation point and a second rotation point, a second yoke having a third rotation point and a fourth rotation point, a first rod assembly connected to the first yoke at the first rotation point and connected to the second yoke at the fourth rotation point, and a second rod assembly connected to the first yoke at the second rotation point and connected to the second yoke at the third rotation point.
