By code, the WF pump should be bonded to same bonding as the pool area and equipment. Much like the suction water velocity, these rules are put in place for safety. Bonding the pump to itself does absolutely nothing. The bonding lug on a pump motor is already connected to the grounding lug so it is redundant.
However, one could argue that if the WF pump is grounded and the pool area is bonded to the main pump which is grounded, by connectivity, the WF will always be at the same potential as the bond and house ground and as long as nothing goes wrong with the grounding wire or bond wire, there should be a minimal risk of shock. But this is not an ideal situation because there could be scenarios where something goes wrong and poses a risk.
80' is a long distance but it shouldn't be that difficult to run a copper wire from a known bonding point to that pump. You don't need to bond all the way back to the main pump if there is a closer point. All the concrete rebar, metal railings, and any other metal should have been bonded together with the equipment. So there might be another point to bond to that is closer to the WF pump.
Are there any metal objects near the pump installation?
Can you take a few pictures of the area around the WF pump?
