Moeller 033400-10 Male Fuel Tank Connector, 1/4 Inch NPT - Johnson/Evinrude Outboard Fitting

The Moeller 033400-10 is a male fuel tank connector built to thread into the fuel withdrawal fitting on the tank side of a Johnson/Evinrude outboard fuel system. It uses a 1/4 inch NPT male thread and is constructed with brass and aluminum fittings for durability in a marine fuel environment. This connector is the tank-side half of the fuel line hookup, designed to mate with the corresponding engine-side connector to complete a secure, leak-resistant fuel supply connection between the portable or built-in fuel tank and the outboard engine.

Because it is designed specifically for Johnson/Evinrude outboard applications, it is a straightforward replacement when an original fuel tank connector has cracked, stripped its threads, or is leaking at the tank fitting. Installation is a simple thread-in swap at the tank's fuel withdrawal port, no special tools beyond a wrench are typically needed. Keeping this connection sound is important for fuel system integrity, since a worn or damaged connector can allow air intrusion or fuel leakage at the tank.
