Ok thats what we needed to know.
The equipment and metal piping is bonded to the bonding grid around the pool. This grid should be under the the walkway around the pool. the original equipment may have had the #8 awg copper bonding wires attached to the bonding lugs of each pump etc...
You need to access the equipotential grid around the pool and then run #8 solid copper wires from each piece of equipment to that grid. Then fasten them to the grid with listed pool bonding fasteners.
Some inspectors will allow you to drive a ground rod next to the pool pump and bond all the equipment to that ground rod then run one #8 from the ground rod to the grid.
The bonding of equipment and metal parts around the pool is not intended to be a fault current path though incindental contact with the egc of the pump circuit is made at the pumps bonding lug. The bonding of metal is to prevent voltage gradients from creating voltage potential differences between the metal parts causing a shock hazard.
Please read this form Mike Holt there is alot to what your doing and you need to be on the right page with all that is required.
Be sure to bond all metal wet niche lights to the grid and the swimming pool junction box. Inspect the potting compund in the metal forming shell if required and replace if found to be deteriorated.
