Foot pounds is torque. Pressure is pounds per square inch (psi). The Mityvac and any reverse bleeder pulls a vacuum (almost) at the bleeder valve/port and the most possible is atmospheric (14.7psi) at standard day (59 deg F.) sea level as atmospheric is on the other side of the reservoir and the pump can probably only pull about 13 psi (14.7 would be absolute vacuum). Reverse bleedeers may not be suitable for these systems if they require 15 psi that I have read mentioned on this forum.
