Need some help on this one.

Rear brake line rusted out, so I ended up replacing all the hard lines myself. That turned out ok. Of course while doing this I noticed the fuel lines were quite rusty as well.

Long story short, I must have stressed the vapor line because I get the smell of gas sometimes after a drive. There are no visible leaks. So in the interest of being proactive, I'm looking at replacing all the fuel lines.

However, there isn't much information to be found on this. Has anyone tackled this or have any tips? I'm assuming the replacements are long gone from Ford.
