Mechanical Fuel Pump Olds 260-455

The Mechanical Fuel Pump Olds 260-455 from Carter is a direct-replacement mechanical fuel pump engineered for classic Oldsmobile V8 engines ranging from 260 to 455 cubic inches. This pump restores reliable fuel delivery to vintage muscle cars, street machines, and restoration projects that rely on mechanical fuel systems rather than electric pumps. If you're rebuilding a carbureted Olds engine or troubleshooting weak fuel pressure on a classic Big Block, this pump delivers the consistent 5.5 psi needed for stable carburetor operation.

Built from durable aluminum construction with a natural finish, the Mechanical Fuel Pump Olds 260-455 handles a flow rate of 30 gallons per hour—sufficient for stock and mildly modified V8 engines. The pump mounts via a standard 5/8-18 inch UNF outlet fitting and accepts 3/8 inch hose barb inlet, making integration straightforward on most classic Oldsmobile engine blocks. Mechanical pumps like this operate on engine camshaft actuation, requiring no electrical power and eliminating complexity—a proven design that eliminates vapor lock issues common in high-heat conditions on street-driven vehicles.

Engine builders, classic car restorers, and fuel system upgraders choose Carter's Mechanical Fuel Pump Olds 260-455 for OEM-equivalent performance on gasoline-fueled applications. Installation fits any Oldsmobile V8 platform using the 260, 330, 350, 400, or 455 engine, whether in original muscle cars, restomod builds, or vintage trucks. The compact 4.4 x 4.4 x 10.15 inch profile and lightweight 1.78 lb construction minimize obstruction in tight engine compartments while ensuring years of reliable operation for enthusiasts who prefer simplicity and proven mechanical technology over modern fuel injection.
