Rollover/Vent Valve

WARNING: This page is about a different car, the 1995 Ford Pickup, 1995 Ford F-Super Duty, and 1995 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

Rollover/vent valve is located on highest point of fuel tank. With fuel in the fuel tank, pressure increases, and the rollover/vent valve releases this extra pressure into the carbon canister. Also, if vehicle is in a rollover situation, the rollover vent valve closes, preventing fuel or fuel vapors to escape from the fuel tank.
