Using these Aeromotive GM LS7 fuel rails is straightforward. First, make sure your engine is a GM LS7 as these rails are specifically designed for it. If you plan to use a -10 AN line, attach the custom ORB - 08/AN - 10 adapter (Part Number 15641). Install the rails using the provided steel mounting brackets, which are custom - made for a perfect fit and easy 'bolt - on' installation. When installing, check the connections of the ORB - 08 ports to ensure they're leak - free. For maintenance, regularly inspect the red anodized finish for any signs of corrosion. If you notice any issues with the ports or the brackets, get them checked immediately. Keep the fuel rails clean and dry when not in use to prevent any damage.
