NOS Late Model Billet Fuel Line Adapters are perfect for wet nitrous systems and virtually any accessory that requires a fuel supply. Engineered to work on late model vehicles with a 3/8-inch OEM quick-connect-style fuel rail, these compact, low-profile adapters fit inline between the factory 3/8-inch fuel rail inlet and fuel-tank supply line, eliminating the hassle of cutting, drilling, or modifying the factory fuel system in order to supply fuel to your nitrous system. The way NOS billet adapters are secured to the OEM supply line is what makes them unique – the spring-clip design that requires special tools has been eliminated. In its place is a special threaded, screw-on base that simplifies both installation and removal, saving you time and aggravation.
