  • One hand “click” connection to OE line
  • O-ring material developed specifically for the same application on factory vehicles to tolerate today’s fuel additives and E85
  • Tether chain keeps secondary retainer clip attached to the adapter so it is always handy (installed retainer can also be safety wired to adapter for additional safety)
