Product Description
Genuine 40518 Fuel Pump (Vintage Rebuilt)
Restore the fuel delivery system of your classic Buick to factory-correct standards with this professionally rebuilt mechanical fuel pump. Proudly Made in the USA, this genuine vintage unit is a period-correct component essential for high-quality restorations. By utilizing high-quality original castings, this rebuilt pump maintains the authentic look and rugged durability that modern mass-market replacements often fail to provide, ensuring your high-displacement V8 receives steady, reliable fuel pressure.
This specific model, 40518, is the verified fitment for late 1960s Buick performance applications. This unit interchanges with part number 40625 (Master 40625M) and serves as the primary replacement for original equipment part numbers 644 0518 and 644 0625. It is engineered to provide the high-volume fuel delivery required by Buick's legendary 400 and 430 cubic inch V8 engines found in the Electra, Riviera, Wildcat, and GS 400 models.
