Moeller Marine Fuel Line Tank Connector 033451-10, 3/8 Inch Barb, Nissan/Tohatsu Engines up to 90 HP

The Moeller Marine 033451-10 is a 3/8 inch barb fuel line tank connector built for Nissan and Tohatsu outboard engines up to 90 HP. It serves as the connection point between the fuel tank hose and the engine fuel line, allowing fuel to pass securely from the portable or built-in tank to the engine's fuel system. The fitting is molded from durable plastic designed to hold up against continuous exposure to marine fuel and the outdoor conditions typical of boating use.

This connector uses a 3/8 inch barbed female fitting, which is sized to slide onto and grip standard 3/8 inch marine fuel line for a tight, leak-resistant seal when properly clamped. It is a direct-fit replacement part for Nissan and Tohatsu outboard fuel systems rated up to 90 HP, making it a straightforward swap when an original tank connector fitting has cracked, worn out, or lost its seal. Because it is sized and rated specifically for this engine range, it is not intended as a universal fitting for other outboard brands or higher horsepower ranges outside this specification.

Moeller Marine Products has built its reputation on fuel system components engineered for reliable performance on the water, and this tank connector fitting is designed to restore proper fuel flow and a secure seal at the tank-to-engine connection point.
