1971–1973 Chevrolet Impala & Chevelle V8 350/400 NOS Fuel Pump #6471181 AC 41217

Available for sale is a genuine General Motors New Old Stock (NOS) Fuel Pump, GM part number 6471181, AC Delco part number 41217, designed for select 1971–1973 Chevrolet Impala and Chevelle models equipped with 350ci and 400ci V8 engines. This original GM service replacement component is an excellent opportunity for collectors and restorers seeking authentic fuel system parts for factory-correct Chevrolet restorations.

The Chevrolet Impala and Chevelle remained among Chevrolet’s most popular vehicles during the early 1970s. The Impala offered full-size comfort, smooth performance, and dependable transportation, while the Chevelle continued its reputation as one of Chevrolet’s most versatile intermediate-sized models. Both vehicles were commonly equipped with the proven 350 and 400 cubic-inch small-block V8 engines, known for their reliability, performance, and durability.

The mechanical fuel pump plays a critical role in the vehicle’s fuel delivery system. Mounted directly to the engine, it draws fuel from the fuel tank and supplies it to the carburetor at the proper pressure needed for efficient engine operation. A properly functioning fuel pump helps ensure reliable starting, smooth idle quality, consistent fuel delivery, and dependable performance under a wide range of driving conditions.

Over time, original fuel pumps can deteriorate due to age, internal diaphragm wear, corrosion, fuel contamination, and normal mechanical use. Common signs of a failing fuel pump include hard starting, hesitation, fuel starvation, poor engine performance, loss of power, and fuel leaks. Replacing worn fuel system components is often essential during restoration or maintenance of a classic Chevrolet.

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 factory specifications, materials, and engineering standards intended by General Motors and AC Delco. Unlike many aftermarket replacements, genuine NOS components provide the correct fit, appearance, and performance expected in factory-correct restorations.

For collectors pursuing originality, genuine GM fuel system components are highly desirable. Authentic service parts help preserve the integrity of the vehicle while ensuring compatibility with original equipment systems.

Whether you’re restoring an Impala sedan, hardtop, convertible, wagon, Chevelle Malibu, station wagon, or performance-oriented model, this NOS fuel pump offers an excellent opportunity to install a genuine GM component designed specifically for these applications.

As original GM service inventories continue to diminish, NOS fuel system parts have become increasingly difficult to find. Original AC Delco fuel pumps are especially valued among restorers because of their quality construction and factory-correct design.

The Chevrolet 350 and 400 small-block V8 engines remain among the most respected powerplants of their era, and maintaining them with authentic GM components helps preserve both reliability and historical accuracy.
