Good Morning,

The line kit is setup for power brake applications. Being that the booster pushes the master out in most cases you wont be able to use them in the manual brake position (Lines are too short). For Low vacuum applications the Hydralic booster setups work great since they tee into the power steering. Check the lines will adapt to this no problem.
