Does a fuel cell need a vent?
The vent is needed! Fuel in the line will cause a line trap not allowing air in or out as fuel level changes also during temp changes. This keeps fuel in the tank in case of a role over. It must vent outside the vehicle. It must run below the bottom of the tank.
Does a diesel tank need a vent?
Bulk diesel storage tanks should be equipped with a vent line to prevent vacuum formation or overpressure in the tank during drawdown or tank filling, or due to atmospheric temperature changes.
What happens if a fuel tank is not vented?
A fuel tank should be vented so you can have an easier time putting fuel in it and because it will vent itself anyway, usually in the form of a vapor locked engine.

Where is purge valve located?
The purge valve is usually located on top of the charcoal canister. In newer cars, the purge valve can be found near the throttle body or near the fuel line.
What does a fuel tank breather valve do?
It is a part of the vehicle’s evaporative emissions system, which is designed to capture and recirculate evaporative emission from the fuel back into the engine bay. It is the job of the EVAP vent solenoid to allow air into the charcoal canister so that the EVAP system can pressurize and function properly.
How do I know if my purge valve is bad?

Your tank has to breathe. In order to breathe, your tank must have a vent somewhere that will relieve both vacuum and pressure. Gasoline expands in volume as it warms up and shrinks in volume as it cools down.
How do you vent a fuel cap?
Stop so it is about even with the center of the edge of the cap. Then drill a small diameter hole, approximately 1/16”, through the edge of the cap perpendicular to the first hole so they just meet up. This allows your vessel to vent, and the 90 degree turn helps keep oil or gas from making its way out.
