Moeller Marine 1/4 in. NPT Fuel Tank Connector 033477-10, Male Two-Prong Clip Style, Mercury 1998 and Newer Engines

The Moeller Marine 033477-10 is a 1/4 in. NPT male fuel tank connector built for Mercury outboard engines from 1998 and newer. It uses a two-prong clip style connection, letting the fuel line detach quickly and securely from the tank fitting without tools, which makes disconnecting and reconnecting a portable tank fast and reliable at the dock or on the water.

Constructed from brass and aluminum with a natural brass and aluminum or clear protective finish, this connector is built to hold up against fuel exposure and marine conditions over repeated use. It threads into the tank side of the fuel line assembly at the 1/4 in. NPT male thread and pairs with the corresponding two-prong clip fitting on the fuel line to complete the connection between tank and engine.

This is a direct fit for Mercury outboard engines built in 1998 and later that use the two-prong clip style fuel connection. If your engine predates 1998 or uses a different connector style, confirm your engine's connector type before ordering, since Moeller offers other tank connector part numbers for different fitment and connection styles.
