Sierra Fuel Pump 18-7254, Replaces 4142885, Chrysler Inboard V-8

The Sierra 18-7254 is a mechanical fuel pump built for Chrysler inboard marine engines. It draws fuel from the tank and delivers it to the carburetor at the correct pressure and volume for reliable engine operation, making it a core component in the fuel delivery system of Chrysler-powered inboard boats.

This pump operates mechanically, driven off the engine, and runs on gasoline fuel systems. It is built to a 142 degree discharge angle with a body measuring 2.125 inches O.D. By 1.500 inches in height, matching the mounting geometry and fuel line routing of the original Chrysler inboard fuel pump it replaces. Sierra manufactures this pump to original equipment specifications so it installs and performs as a direct replacement without modification to existing fuel lines or mounting hardware.

As a direct-fit replacement for Chrysler inboard V-8 marine engines, the Sierra 18-7254 is intended for boat owners and marine technicians replacing a worn, leaking, or failed factory fuel pump. Installation follows the same bolt pattern and fuel line connections as the original Chrysler unit.
