Radiator Hose, Black Heater Hose, Red Battery Cable

This one is nice due to the fact you get a few different sizes in on offering. If you plumb of wire your models you know you can never have too much of these items. Buy two at a time as you will use them up quick.

Braided Line looks nice but you don't want to build every kit exactly the same but you do want every build to look as real as possible and this Hose kit is the ticket.

With a slight amount of care, (& patience), these products can quite effectively be used to simulate the cables & hoses normally found under the hood.
