My stock Miata fuel pump connector and wiring melted out of my 200k mile Miata from running a DW300 high flow fuel pump. I have done the Trackspeed Engineering fuel pump relay mod but the increased current melted out the stock plug! I used the Radium Engineering fuel sender kit to bulletproof the pump wiring connections and allow much more current (safely) to the pump.
