Fuel Filler Cap: Description and Operation
Operation
OPERATION
The fuel filler cap incorporates a two-way relief valve that is closed to atmosphere during normal operating conditions. The relief valve is calibrated to
open when a pressure of 17 kPa (2.5 psi) or vacuum of 3 kPa (12 in. Hg) occurs in the fuel tank. When the pressure or vacuum is relieved, the valve
returns to the normally closed position.
CAUTION: Remove the fuel filler cap to release fuel tank pressure before disconnecting any fuel system component.
