What is the purpose of fuel tank vent valve?
When the engine is running, the fuel vapors are purged from the canister and burned in the engine. The vent control valve (solenoid), or simply vent valve controls the flow of outside air in and out of the charcoal canister. In some cars, it’s called Canister Close Valve (CCV).
How do you replace a fuel tank vent?
After the epoxy has set cut the nipple of off the old vent valve. Then insert the cut side of the nipple into the hose leaving enough space for the locking clip on the fitting. This is the finished product, it is stronger than the oem fitting and sealed back up nicely.
How to check a gas tank vent valve?

How does a fuel tank breather valve work?
Disconnect the canister vent line to the gas tank, and try blowing through it. Push a length of small-gauge plastic tubing or large heavy wire through the vent pipe, to check for a physical blockage. Similarly, it is asked, what does a fuel tank breather valve do?
Is there a way to repair a broken vent valve?
As you can see it was snapped right off, and there is really no way to repair it, I even tried gluing it back together with loctite 404 last week to no avail.

Gas tanks require a vent-atmospheric pressure must be allowed to enter the tank to prevent creating a vacuum as fuel is removed from the tank. However there is a problem with gas tank vents. They work both ways: They let air in and they can also let gasoline vapor out.
What is is/why fuel tank venting?
You most likely know that fuel tanks need ventilation in order to allow the fuel to continue to pump without causing a vacuum . This can either be through the gas cap itself, or via some sort of breather tube.
What is a purge vent valve?
The purge valve (also known as a solenoid) is an essential piece of a vehicle’s Evaporative Emission Control (EVAP) system. This series of parts helps to prevent potentially toxic fuel vapors from being vented into the atmosphere.
What is the fuel tank ventilation valve?
The fuel tank vent valve is part of a vehicle’s evaporative emission control (EVAP) system, which lowers the amount of vapors released from the fuel tank into the atmosphere. The fuel tank vent valve controls the flow of air getting into and out of the charcoal canister.
