In Tank Assembly This Fuel Pump Module has been updated, replacing the external Filter/ Regulator unit with an internal filter & regulator. The removal of the external regulator eliminates the need for the grounding wire connected to the grounding tab on top of unit. The exposed terminal on the grounding wire should be covered with electrical tape and secured to the wiring harness. This will not affect the operation of the Fuel Pump Module. - This Fuel Pump Module has been updated, replacing the external Filter/ Regulator unit with an internal filter & regulator.
