I ran a dedicated 12/2 w/g 20 amp GFCI protected outlet for a cord and plug connected water jet tub. All the plumbing is plastic. The motor has a bonding lug on it. What are the requirements for bonding this application. My thoughts are that I'm done with install or do i need to run the #8 back to panel from the bonding lug located on motor.

On 95% of the installations, you are fine.
I have encountered some Jacuzzi brand hydrotubs where the mfg. instructions call for a #8 bond to panel, but such requirements are rare.
Check you manufacturer instructions.
(The lug on the motor is often there because it is the same motor used for swimming pool installations)

I have seen those, too and have had to run a #8 back to the panel.

And which section of the NEC did the inspector quote for this requirement? Or was it in the MFR's instructions?

If the ground wire that you ran is bonded to the motor then you have no problem. You need a ground fault current path. GFCI protects personnel not equipment.

As per instruction. Also, solid was specified IIRC.
The requirements are in 680.74. If you have metal piping in the walls connected to this tub, you'd need to connect to those. It its all plastic, then you're probably done. Anything else touching the water should have been bonded by the tub maker.
