5/16" Fuel Line - MADE IN USA, used for balance tube
5/16" Fuel Hose - MADE IN USA. This is really good quality stuff. I don't skimp on fuel hose. This is what I use in my cars and both my kids' cars. This is used for balance tube to connect the two manifolds. Some kits use 1/4". some use 5/16", some use 3/8" for balance tube. All use approximately 30". Order 3' and you'll have plenty.
