This Diaphragm Pump mounts on the front all 64-73 Autolite 2V carbs as well as 64-67 Autolite 4V Carbs. These commonly fail with today's ethanol fortified gas, especially when sitting for extended periods of time. Complete failure will cause dangerous fuel leaks, but many times these will affect performance well before a leak actually starts. Good idea to replace every 2-3 years or if sitting for 6 months or more.


  • OEM-style, direct-fit replacement pump
  • Will not degrade when exposed to modern fuels
  • Made of high quality materials
