From the outside nothing looks to be "hacked", it is a complete fuel injection swap, tank, intake computer etc. on a carb motor so there's a chance some things got bypassed. What would I be looking for to see if that NO switch has been bypassed? I know jumping the test connector bypasses the afm and I think the CO relay but that also allows the pump to run with the ignition in just the on position, mine only comes on in the start position and the connector is not jumped.
