Fuel Pump Resistance Wire Bypass
The resistance wire is in the ground side of the 4-wire harness in the hatch area inside the car. The black wire turns into a white resistance wire a few inches from the lower floor grommet. Tag into the far side of the white-black junction (towards the fuel pump) with a 12 gauge wire and run that back to a good chassis ground.
Additionally run a 12 gauge (or larger) wire to the fuel pump relay from the harness take-off that goes to the chassis-mounted fuel pump back to the power wire to the in-tank pump.
The stock, low-pressure pump will pull about 4 Amps at peak power and the 255 LPH pump will pull about 17 Amps at full pressure. So the stock power AND ground wires are not large enough.
Some pics of the ground resistor bypass.
