Sierra 18-8866 Fuel Pump for Mercury 4-Stroke Outboards, Replaces 899106T01, 892874T01

The Sierra 18-8866 Fuel Pump is a direct-fit replacement fuel pump built for Mercury 4-stroke outboard engines. It delivers fuel from the tank to the carburetor or fuel rail at the pressure and volume the engine needs to run cleanly, and it is engineered to meet or exceed the performance of the original equipment pump it replaces. The housing and internal components are made of durable plastic construction sized to fit into the factory fuel line routing without modification.

This pump features a threaded inlet connection and a barb-or-flare outlet connection, each sized at 5.55 millimeters, and it mounts using a bracket mount configuration in the engine's fuel delivery circuit. It is designed to run on gasoline. Compact overall dimensions of 0.39 x 0.39 x 0.39 inches allow it to fit the same footprint as the original Mercury fuel pump, so no bracket or line modifications are needed during installation.

Every Sierra fuel pump is backed by a 90 day manufacturer warranty, giving buyers confidence when replacing a worn or failing fuel pump on their Mercury 4-stroke outboard.
