Fuel Filler Cap: Description and Operation
FUEL FILLER CAP
Fuel Filler Cap
The fuel filler cap (Figure 100) is used to prevent fuel spill and close the evaporative emission/fuel system to atmosphere. Some vehicles may have a
Fuel Cap Off Indicator Lamp (FCIL) in the instrument cluster which will illuminate when there is a failure in the vapor management system that may
be due to the fuel filler cap not being sealed.
