I'm in the middle of doing my rats nest and simplification and I wasn't sure if the hosetechniques kit that i have will work for the fuel vapor lines on the rats nest and their website didn't provide a whole lot of answers so i was hoping someone on here might know. thanks.

They will work. However, those lines could see some gas in them (hence the aluminum check valve to the UIM instead of a plastic one). It shouldn't be a steady flow of fuel like the actual fuel lines so it shouldn't hurt them.
