Using this IAG PTFE fuel line kit is a breeze. First, make sure you have the IAG top feed fuel rails and OEM or IAG TGV housings as they're required for installation. The kit comes pre - assembled to the right lengths, so you don't need to cut or assemble hoses. You can use it with modern ethanol fuels like E85. When installing, use the included bracket to mount the Aeromotive Fuel Pressure Regulator (which you need to buy separately) on the driver - side strut tower to replace the factory regulator. As for maintenance, since the PTFE coating resists heat and corrosion, it's quite durable. But still, check the lines regularly for any signs of wear or damage. If you notice any fuel smell, it might be a sign of a problem, so inspect the lines right away.
