Required when upgrading fuel pumps. Running high boost on ethanol will require a higher demand of fuel and the stock pump is not up to the task. This installs in minutes and is none intrusive. Simply unplug the factory plug, plug this kit into the factory wiring and into the fuel pump connector, ground the eyelet to the fuel pump protection bracket, and test the pump.
This product listing does not include the fuel pump; replacement rewire harness ONLY.
