Genuine 40334 Fuel Pump (Vintage Rebuilt)
Restore the fuel system of your classic International Harvester or Palmer Marine engine to factory performance 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 original heavy-duty castings, this rebuilt pump maintains the authentic look and rugged durability that modern mass-market replacements often fail to provide, ensuring your V8 receives steady, reliable fuel pressure.
This specific model, 40334, is the verified fitment for a wide range of 1959-1968 International (IHC) truck and marine applications. It is the designated fuel pump for IHC V-series engines, including the 266, 304, 345, and 392 cubic inch V8 powerplants. Additionally, this unit is the correct application for Palmer Marine V8 engines (PB-V series) derived from the International block. This pump serves as the primary replacement for original equipment part number 644 0334 and interchanges with Carter model M3296S, featuring an offset filter configuration to accommodate specific engine clearances.
