Wasn't a random guess.. It wasn't a sure answer but it was something that I have heard and was trying to give input. I don't know what your issue is. I'm just trying to help once in a while and you seem to always have a problem with me.
i laugh , even though its not a laughing matter , that if you tell people that's a gas tank vent tube , even though you don't really know, and they believe you , then they route their ACTUAL vent tube up through the trunk floor into the car , thinking that's how it is supposed to be , then they light a cigarette , BOOM up goes the car and their LIFE. you would never run a gas tank vent tube INTO the vehicle
