Sierra Fuel Pump 18-7286 for Volvo Penta AQ120B, AQ131, AQ140A, AQ151, AQ230, AQ250 Engines

The Sierra 18-7286 is a mechanical fuel pump built for Volvo Penta marine engines, replacing the original engine-driven pump that feeds fuel from the tank to the carburetor. It mounts at the rear of the engine and is cam-driven, pulsing fuel forward under the engine's own operating cycle rather than relying on an external electric supply. This makes it a direct, drop-in mechanical replacement for boats running the Volvo Penta AQ and BB series powerplants listed below.

The pump carries a UPC of 030999322579 and is sold as a single complete unit, ready to bolt into place without additional pump-rebuild kits. Because it is engine-driven, proper installation depends on matching it to one of the specific Volvo Penta engine models it is designed for; using the correct pump for your engine model ensures correct fuel delivery pressure and volume for the carburetor it feeds.
