Braided PTFE Fuel line – Stealth Edition

Be careful when buying Nylon and Stainless Steel lines, because they are not all the same!

Most of the braided Nylon and  Stainless Steel lines and fittings that you can buy actually have a rubber (EPDM or NBR) interior. Some competing products advertise a special coating on the inside of the rubber to make them resistant to ethanol and certain other chemicals (Often see as “E85 Safe”).  You should only use materials that are 100% resistant to the chemicals for your fuel, Brake, and clutch lines such as Ptfe period.

PTFE with Nylon or Stainless Steel has much greater chemical and pressure resistance compared to the Nylon and Stainless Steel lines that have rubber on the inside. They’re a little harder to install, but are practically invincible. PTFE is chemically inert!

Braided Nylon or Stainless Steel PTFE lines are great for replacing many factory rubber hoses such as rubber fuel lines, brake lines, and clutch lines. PTFE / Teflon does not deteriorate or bulge with age like rubber does( this can cause clogged injectors and engine damage), and has far superior chemical resistance. The Nylon or Stainless Steel outside keeps the inner diameter uniform, allowing faster and more efficient fluid transfer (this means a smoother fuel delivery which can actually be felt in some cases) The stainless steel outside also keeps the lines looking shiny and new, While the Nylon gives you that Stealth look! Both lines look professional at all times while preventing damage to the inner hose.

    haven’t received it yet or more info on when it’s shipping or how long until it’s recalled because it was lost beginning of the month

    I wish I could review the part itself but the fittings were backorder and then backordered again and since I needed the fuel line to get my car back on the road, KDMT had SXTH send me a fuel line. The communication was good and their service was everything it could be all things considered. I understand things happen and I respect how they handled a less then awesome situation. I’ll be back to buy again due to their top notch service when things were going wrong

    The line works great! You will run into a few issues that kdm tuners video does not show you. The bolt side of the an fittings need to be shaved down to fit on the high pressure fuel pump and the low pressure fuel pump. All in all once that is fixed the install is a pretty smooth process!
