Hi,
I have a 2005 chevy Silverado 1500 and was wondering should I replace the whole filler neck or just the overfill hose that's broke. Is this a pain in the rear to do.

 

not sure what a overfill hose is? are you referring to the refueling vapour recover pipe that is part of the filler neck? post a pic

the vapour recover pipe can't be open to the atmosphere or evap leak codes will set. Its should be replaced for safety...what if you have a rollover. Its not a bad job to replace.

 

Yeah that must be what it is. I saw the hose hanging from the filler neck and just assumed it was for overflow. Where does the hose go to, the top of the gas tank?

 

yes.
its function is to create a vacuum at the top of the filler neck when refueling...this draws fuel vapour down into the tank instead of venting up into the air.

 

so I looked at the fuel hose today connected to the filler neck and its just a hose that is capped at the top of the hose? Its not actually into the filler neck itself its just attached to the filler pipe with a bracket. unsure where it goes or what its to. Any help would be appreciated.
Thanks kev

 

go to rock auto, build your vehicle, find the part in question and post a link. hard to say without seeing what you are talking about.
