When I was filling up right now I noticed that gas was leaking out from approx. right under where the nozzle goes in the tank from under the truck. If I pumped it slow it would not leak but when I sped it up it started leaking. Any ideas?

 

Anyone??

 

Answer in the Fuel tank Vent line post.

 

Mine is leaking by the neck though, not the tank...

 

Check the vent line hosethat runs on the side of the bigger rubber hose. Might be crack!

 

What roverwoody said, also check your trickle valve seal.

Vapor/vent line. Mine did same thing.

What year is your truck? Some have fuel tank recall and you could get both done at same time.
