Using these Aeromotive fuel rails is straightforward. First, make sure your vehicle is a 2004 - 2006 Subaru 2.5L STi. The rails are designed for easy 'bolt - on' installation, so simply attach them using the provided steel mounting brackets. If you want to use - 10 AN line, you'll need the custom ORB - 08/AN - 10 adapter P/N 15641. When installing, ensure all connections are tight to prevent leaks. For maintenance, regularly check the red anodized finish. If you notice any signs of corrosion, clean the rails gently with a mild cleaner. Also, inspect the ports and connections to make sure they are in good condition. If you have any issues with the flow or performance, check for any blockages in the 5/8” ID through bore.
