Undersized wiring is the quiet reason a good pump underperforms. Voltage drop at the pump costs you flow exactly when the engine is asking for the most, and no amount of pump upgrade fixes it. This kit runs 10 gauge with a proper relay and breaker so the pump sees what the battery is actually putting out.
