Fuel Line is cheap but very important. Made of Silicone, this type of fuel line (tubing) is used for all grades of Nitro fuel. While this type of tubing is tough and heat resistant proper care is necessary. One pin hole or leak in the fuel line can mean a tough day for any modeler!

Sold by the foot at about $0.75
We have found Prather brand line to be the best Silicone fuel line available. It is pink in color and available in Small, Medium or Large. See below for a list of size uses.
Small: Not used very often
Medium: Used the most for the transfer of fuel from the tank to the engine and from the pipe to the tank.
Large: Used most often for plumbing water to the head on the engine. The large size carries a good supply of water to and through the engine's water jacket in the head.
