Pressure Relief

  • Prevents fuel vapors from exiting the fuel system under normal operating conditions
  • Allows an escape path for pressure in an impact situation where the fuel tank has collapsed
  • Permits pressure to escape in the event of a Vapor Management System malfunction such as a plugged vent line

Vacuum Relief

  • Prevents fuel vapors from exiting the fuel system via the fill tube under normal operating conditions
  • Allows an alternative path for air to flow into the fuel tank in the event that there is an obstruction in the Vapor Recovery and/or Vapor Management Systems
  • Permits fuel system to normalize during natural vacuum situations  For example, a hot fuel tank being cooled down by a drive through car wash

Lost Motion

  • During a crash the cap handle is allowed some freedom to rotate (from 60° to 180°) while maintaining proper O-ring compression
  • Aids in the prevention of potential fuel leakage in a crash or impact

Torque Override

  • Aids in proper installation of fuel cap
  • Provides audible “click” for customer
  • Allows for proper O-ring compression

Break Away Groove

  • Allows for O-ring to maintain proper compression during a crash or impact even is some of the cap is broken away
  • Prevents potential fuel leakage during a crash or impact
