Fuel Tank Pressure Release Valve: Description and Operation
Fuel Tank Vent Valve
The fuel tank vent valve, located in the rear of the vehicle by the fuel tank, is a pressure / vacuum relief valve. When fuel tank pressure exceeds a
specified pressure, the valve will open allowing tank pressure to bleed off. When the fuel tank is in a vacuum condition, the vent valve will open when
the vacuum is within a specified range allowing fresh air to be pulled in.
