Abstract
An evaporative emission control system for an automotive vehicle comprises an integrated roll-over valve and vapor pressure sensor assembly mounted by means of a grommet in the top wall of the vehicle's fuel tank. The vapor pressure sensor forms part of an on-board diagnostic system for testing the integrity of the tank and vapor collection canister against leaks.
