PTFE Hose Construction
IAG’s PTFE fuel lines use Fragola 6000 series PTFE hose with stainless steel reinforcement and a black nylon outer covering to prevent scratching. The lines are pre-assembled to application-specific lengths for a direct installation — no cutting or fitting assembly required. Working pressure is 2000 psi (burst 8000 psi). PTFE does not allow permeation of fuel vapors, which eliminates the fuel smell that other hose types can exhibit. The hose is compatible with all automotive fuel types including E85.

Application-Specific Lengths
Every line in the IAG kit is pre-assembled to the exact length needed for the 08-14 WRX / 08-21 STI application. There is no cutting, no end assembly, and no guesswork — the lines connect directly to the IAG fuel rails and the factory fuel system hard lines.

Pairing with IAG Rails
This line kit is designed to work with IAG’s V3 Top Feed Fuel Rails (IAG-AFD-2102 series). The fittings and lengths are matched to the rail specifications for a direct, correct installation.

Why Choose IAG Performance

IAG Performance has been building Subaru-specific engine and drivetrain components since 2001, and in that time they have become the standard by which serious Subaru builds are measured. Based in Westminster, Maryland, IAG designs, machines, and assembles their products in-house using Haas CNC equipment and their own engineering team. Their catalog spans everything from short blocks and long blocks rated to 1150 BHP all the way down to the fuel system, oiling, and drivetrain hardware that keeps modified Subarus running reliably for years. Every IAG product exists because a problem needed a better solution than what was available — and the engineering shows.

The RallySport Take

The IAG PTFE fuel line kit is the correct line solution when building an IAG top-feed fuel system on the 08-14 WRX or 08-21 STI. Pre-assembled, E85 compatible, and built to the same quality standard as the rest of IAG’s fuel system components.
