Using this fuel line kit is straightforward. First, make sure you have all the required parts, like the IAG Top Feed Fuel Rails, Aftermarket TGV Housings, and the COBB Flex Fuel Sensor. If you want to use the Aeromotive Fuel Pressure Regulator, you'll need to buy it separately and use the included bracket to mount it on the driver - side strut tower. The lines are pre - assembled to fit your 2008 - 2021 Subaru STI, so installation should be easy. Just match them to the right places. When it comes to maintenance, since the PTFE material resists heat and corrosion, you don't have to worry too much. But it's a good idea to check the lines regularly for any signs of wear or damage. Also, keep an eye on the fittings to make sure they're tight and not leaking. If you notice any fuel smell or other issues, it's time to inspect the lines right away.
