This Fuel Pump Mounting Kit includes two rubber shock mounts, four matching locknuts, and a ground strap. Provides quieter pump operation and allows Facet Cylindrical pumps to be used on positive-ground vehicles.
For positive-ground hookups:
1. Connect the power (negative) wire from the vehicle to the top post of one of the shock mounts so that it makes contact with the pump mounting flange.
2. Connect the power (positive) wire from the pump to the bottom of one of the shock mounts so that it makes contact with the chassis of the vehicle. The ground strap in this kit will not be used.
