I'm going to be running the fuel lines soon and I was thinking of using nylon lines all the way. Its the return style fuel injection and I'm going to use the intank pump from the Mark VIII which originally had nylon lines on it before going to steel somewhere down the line. Has any one used the nylon line? I think most new vehicles use it.

 

Just bumping this with a more specific question. The stock nylon lines are connected to a quick connect fitting with a ****** end. I read that all you have to do is heat in boiling water then slide it on the ****** end and when it cools its sealed and holds tight. Does this work for normal ****** ends like for a spring lock fitting or fuel filter or do you have to use the seal clamps that are made for the nylon line?
