Sierra Fuel Elbow 18-8067, 90 Degree Brass, 3/8 Inch Barb x 1/4 Inch NPT

The Sierra Fuel Elbow 18-8067 is a 90 degree brass fitting built to connect fuel line hose to a fuel port at a right angle, keeping the hose run tight and free of kinks in confined engine compartments. One end is a 3/8 inch hose barb that a fuel line pushes onto, while the other end is a 1/4 inch NPT threaded connection that screws directly into a fuel pump, carburetor, fuel filter, or fuel tank fitting. The elbow is machined from brass, a material chosen for fuel system fittings because it resists corrosion from ethanol-blended fuel and marine moisture better than many alternatives, while still holding a tight, reliable seal at the threaded joint.

Because the barb and NPT sizes on this elbow are common across many outboard and inboard fuel systems, it works as a general-purpose replacement or upgrade wherever a 3/8 inch barb to 1/4 inch NPT 90 degree connection is needed, rather than being tied to one specific engine model. Sierra part number 18-8067 identifies this exact fitting for ordering.
