When designing the IAG Fuel Line Kits the goal was to take the worry and confusion out of properly setting up Subaru fuel delivery. The IAG Fuel Line kits provide everything you need to successfully feed your engine with enough fuel to meet your horsepower demands. Made in the USA and constructed of chemical resistant PTFE, these line kits are easy to install and don’t require any cutting or hose assembly. Each line kit is compatible with modern ethanol fuels, including E85. These kits are designed to work with aftermarket Fuel Rails and the aftermarket Adjustable Fuel Regulator, for precise control of your fuel pressure.
