If I have a conduit run that taps off with liquid tite flex do I need to pull a bonding wire through the liquid tite flex to meet the NEC requirements for bonding

Maybe. We need a lot more information to answer the question. See 250.118(7).

More informatin on this subject. We have a control panel with rigid conduit going out to feed motors. The motors are tapped off of the rigid conduit via FS boxes and T fittings with liquid tite flex.

Is the liquid tite flex suitable for bonding. I know that the rigid conduit is suitable, but I am not sure on the liquid tite flex.

By our Canadaian Electrical Code we are required to pull a bonding wire in the liquid tite flex to meet the requirements of bonding - we are not allowed to rely on the liquid tite flex core as a bond.

If the liquidtight is not supported within 12" of each end, a bonding jumper will be required.
