Why Upgrade Your
Fuel Lines?
Modern high-performance fuels and high-pressure injection systems push standard plumbing past its engineered limits.
Ethanol Compatibility
High ethanol concentrations in E85 demand chemically inert plumbing. Our PTFE inner core is 100% immune to alcohol degradation, race fuels, and fuel system corrosion.
Fuel Vapor & Garage Smells
Elastomeric hoses can experience microscopic hydrocarbon weeping over time. Dense PTFE provides zero vapor permeation, eliminating persistent gas odors.
High Underhood Thermal Resistance
The stainless steel and nylon outer braid combined with PTFE withstands up to 230°C, ensuring reliable routing alongside high-output exhaust manifolds and downpipes.
The Complete 28-Piece Kit
Buy Once. Install Once. No Missing Pieces.
- 1 x 26FT (7.9m) 6AN Braided PTFE Hose (Slim 0.47" OD)
- 12 x T6061 Aluminum Fittings (Straight, 45°, 90°, 180°)
- 4 x EFI Quick Disconnects (3/8" & 5/16") with Laser-Etched IDs
- Included Tools: PTFE Reaming Tool & Custom Wrench
Install It Right The First Time.
PTFE is rigid. We include a specialized Reaming Tool in every box to make assembly flawless and leak-free.
-
01
Slide the Collar FIRST
Cut the hose cleanly, slightly fray the outer braid, and slide the socket collar over the hose.
-
02
Use The Reaming Tool (Crucial)
Insert the included reaming tool to open up the PTFE core. Never force a fitting into an un-reamed hose.
-
03
Insert Olive & Tighten
Push the brass olive under the braid, insert the fitting core, and tighten using the provided aluminum wrench.
-
04
Pressure Leak Test
Always pressure test your assembled lines with compressed air before routing them in the vehicle.
PTFE vs. Other Materials
Understanding material differences ensures you choose the right plumbing for your specific horsepower and application needs.

Choosing Between Rubber and PTFE?
While high-pressure PTFE is mandatory for high-demand EFI conversions, turbo setups, and corrosive E85 racing fuels, standard reinforced rubber remains the proven, cost-effective standard for gravity-fed carburetors, utility engines, and small machinery. If you are servicing outdoor power equipment, explore our dedicated rubber fuel line for lawn mowers and low-pressure fuel systems.
