Allows you to attach a -6 AN hose fittings directly to your factory NA 5/16" hardlines. We recommend under the car just before the firewall. If you'd like to run a complete AN line configuration we recommend adapters available in our Fuel Delivery section. The NB will only use one of these fittings as it's a dead headed or non-return style fuel system.

**Notice: The fuel line cutter does not come with these fittings, it's an example of the tube cutter you'll use.
