📦Package Contents:

  • 6AN PTFE Fuel Hose (25FT)
  • 6AN Straight Fittings (6)
  • 6AN 45° Fittings (2)
  • 6AN to 3/8" Quick Release Fittings (3)
  • 6AN to 5/16" Quick Release Fittings (1)
  • 6AN to 3/8" NPT Fittings (2)
  • Auxiliary Installation Tool
  • Universal LS Swap & EFI Compatibility: This 6AN fuel line kit is purpose-built for LS engine swaps, aftermarket EFI conversions, and turbocharged fuel systems. It works with carbureted, EFI, return-style, and dead-head fuel setups. Before ordering, confirm your fuel rails and pump use 6AN fittings and that you are comfortable working with PTFE hose — this is not a direct OEM replacement line and requires assembly.
  • E85-Proof PTFE Inner Core: Unlike rubber fuel hose that swells and degrades with ethanol-blended fuels, the PTFE (Teflon) inner liner is chemically inert. It handles E85, methanol, pump gas, diesel, oil, and coolant without breaking down — no fuel smell in the cabin, no black debris in your injectors, and no hose replacement every season.
  • 1500 PSI Headroom You Will Never Outgrow: Rated for 1500 PSI working pressure with a 4500 PSI burst rating, this hose exceeds anything a street or strip fuel pump can output. Whether you are running a stock LS pump at 58 PSI or a 1000+ HP aftermarket system at 80+ PSI, this line stays sealed. Temperature tolerance spans -76°F to 446°F, covering cold starts to under-hood heat soak.
  • Complete AN Fitting Set — No Extra Trips to the Parts Store: Every fitting you need is in the box: (6) straight 6AN hose ends, (2) 45° hose ends, (3) 6AN-to-3/8" quick-disconnect adapters for GM fuel rails, (1) 6AN-to-5/16" QD for return lines, and (2) 6AN-to-3/8" NPT adapters for pumps and filters. Includes an installation tool to seat the ferrule properly.
  • 3-Layer Braided Durability: The hose is built in three layers — a smooth-bore PTFE inner core for unrestricted flow, a stainless steel braided mid-layer for pressure containment and kink resistance, and a nylon outer jacket that protects against abrasion, UV, and under-car debris. Available in all-black or black-red finish to match your engine bay.

DESCRIPTION

PTFE vs. Rubber: Why E85 Changes Everything

Ethanol-blended fuel is the standard now, and a rubber hose was never designed for it. Over time, E85 attacks rubber from the inside — causing swelling, micro-cracks, and vapor permeation. That fuel smell in your garage? That is ethanol vapor bleeding straight through the hose wall. The PTFE inner core in this kit is zero-permeation: the fuel stays inside the line where it belongs. No smell. No degradation. No mystery, fuel pressure drops after a few thousand miles. If you plan to run E85 now — or might switch later — PTFE is the only material that does not ask you to replace your fuel lines when you change fuels.

What the 3-Layer Construction Actually Does

Each layer has a job. The PTFE inner liner handles chemical resistance and smooth flow — its non-stick surface means zero internal buildup over time. The stainless steel braided mid-layer is your pressure backbone, absorbing the 1500 PSI rating and preventing the hose from ballooning under pump surge. The nylon outer jacket is the layer you see — it protects the steel braid from road grime, salt, UV, and physical abrasion without the sharp edges bare stainless braid leaves on everything it touches. Together, they give you a fuel line that lasts the life of the build, not the life of a rubber hose.
