This braided 4AN hose is a lightweight evolution of the stainless steel used since the early 1940s. Easy to work with and maintain, it won't cut your hands to bloody pieces! It will take the heat and pressure of a modern racing engine, however.
Note: USRT regularly uses this line variant in our water/methanol injection systems. With 50/50 mixture, regular 1/4" Nylon tubing is quite adequate. However, for heavy methanol usage, safety cannot be compromised.
