Abstract
A one quarter turn fuel cap assembly is provided with a fuel cap and a sleeve. The assembly is closed by rotation of the cap through a one quarter turn. Following rotation, a cam permits a spring disposed in the fuel cap to expand and engage a seal against a rim of the sleeve to close the assembly without rotating the seal relative to the ring.
