File Line Vent Valve

[EThayres]

Hi All,

I pulled a 0456 code last week. I already checked the gas cap.

Before I drop $200 plus on a new File Line Vent Valve. During the last 12 months whilst the gas tank, the pump sometimes shuts off before the car is full.

Is this one of the causes of a bad FLVV?

Thank you,
Ed
