The IAG Fuel Line Kits are engineered to simplify and optimize fuel delivery for Subaru engines. Each kit includes everything needed to reliably feed your engine with enough fuel to meet high-performance demands. Made in the USA from chemical-resistant PTFE, these pre-assembled lines require no cutting or modification, making installation straightforward. They are fully compatible with modern ethanol fuels, including E85, and work seamlessly with aftermarket fuel rails and adjustable fuel pressure regulators for precise fuel control.
These PTFE fuel lines are compatible with OEM or IAG TGV housings with sensors and motors installed, requiring no modifications to the tumble generator valve assemblies.
Constructed from polytetrafluoroethylene (PTFE), a high-density, heat-resistant, and hydrophobic material, these lines prevent fuel permeation and resist degradation over time, even when exposed to ethanol-based fuels.
