1953–1954 Chevrolet Corvette C1 NOS Dual Vacuum Fuel Pump #5592675 AC Type 9797

Available for sale is a genuine General Motors New Old Stock (NOS) Dual Vacuum Fuel Pump, GM part number 5592675, AC Type 9797, designed for select 1953–1954 Chevrolet Corvette C1 applications equipped with the original Chevrolet inline six-cylinder engine. This authentic GM service replacement component is an exceptional find for collectors and restorers seeking factory-correct fuel system parts for one of America’s most iconic sports cars.

The 1953 Chevrolet Corvette marked the beginning of an automotive legend. As Chevrolet’s first production sports car, the Corvette introduced fiberglass body construction and distinctive styling that immediately captured public attention. The 1954 Corvette continued this groundbreaking design while expanding production and refining the vehicle’s overall quality. Today, these early C1 Corvettes remain among the most sought-after and historically significant American collector cars.

The dual vacuum fuel pump is a critical component of both the fuel delivery and vacuum systems. Unlike a standard mechanical fuel pump, the dual-action design performs two important functions. It supplies fuel from the fuel tank to the carburetor while also providing supplemental vacuum assistance for vacuum-operated accessories. This design helped maintain consistent accessory operation during periods of low engine vacuum.

The fuel section of the pump delivers a steady flow of gasoline to the carburetor, ensuring reliable starting, smooth idle quality, and proper engine performance. The vacuum section helps support components that rely on vacuum pressure, contributing to dependable operation under varying driving conditions.

Over time, original fuel pumps can suffer from internal diaphragm deterioration, worn check valves, corrosion, contamination, fuel leakage, and general mechanical wear. Common symptoms of failure may include hard starting, poor fuel delivery, engine hesitation, reduced performance, weak vacuum operation, and fuel system leaks.

This component is a true New Old Stock (NOS) GM service replacement part. Manufactured during the original production era and never installed on a vehicle, it retains the original engineering specifications, materials, and quality standards intended by General Motors and AC. Unlike modern reproductions, genuine NOS components provide factory-correct fit, appearance, and functionality.

AC was one of General Motors’ primary suppliers of fuel system components and produced many of the original fuel pumps used throughout Chevrolet’s product lineup. Authentic AC service parts are highly valued by collectors because they represent the same components supplied through Chevrolet dealerships during the vehicle’s service life.

For enthusiasts pursuing concours-level or factory-correct restorations, original fuel system components are essential. Using genuine GM and AC parts helps preserve the authenticity of the engine compartment while ensuring compatibility with the original mechanical systems.

The 1953 and 1954 Corvette models occupy a unique place in automotive history, and maintaining original specifications is critical to preserving both their historical significance and collector value. Genuine NOS service parts play an important role in achieving that goal.

Whether you are completing a show-quality restoration, maintaining a survivor vehicle, or replacing a worn original component, this NOS dual vacuum fuel pump offers an outstanding opportunity to acquire a rare and authentic GM service replacement part.
