ive been thinking about buying some 3/8 tube to use to run under my intake manifold to and from the rail to the FPR.and then using a braided line for flexibility anywhere the line requires flexibility.has anyone done this before?i cant really think of any downsides to giving this a shot?anyone have an opinion?

thanx,
aaron

 

Stock fuel injected rotarys have hard lines integrated within the factory vacuum nest under the intake. So this is nothing new. You'll be fine. The only reason you even have flex lines in the fuel system is for chassis and engine flexing.
