Earl's Performance introduces Vapor Guard OEM quick-connect fuel rail adapter fittings. These fuel line fittings offer an easy way to re-use existing OE fuel rails, fuel filters, and other components when doing an engine swap—or upgrading to Vapor Guard (or other AN plumbing). Each fitting has a -6 AN male flare and a metal retainer nut for a secure leak-free connection to the 5/16 or 3/8 in. SAE-style fuel tube. The adapters are machined from 6061 T6 aluminum with a black anodized finish. Order the size needed for your application. Additional product features and benefits: * Allows easy transition from AN plumbing to OEM late model fuel rails, fuel filters, and other fuel system components * Metal retainer nut is more secure than plastic clip * Choose from adapters that fit OE 5/16 or 3/8 in. tube on fuel rails (and other components) * Economically priced * Ideal for use with Earl's Vapor Guard hose and hose ends * Slim design for extra clearance
