Running a high draw electric fuel pump off a switched ignition wire is how dashboards catch fire. This kit gives the pump its own relay-switched circuit fed through a 30 amp breaker, with heavy gauge wire long enough to reach a rear mounted pump, so the trigger wire only has to carry the signal current.
