The Aeromotive Atomic Hex Drive is a 12 GPM mechanical fuel pump built to feed serious EFI and carbureted engines on gasoline, ethanol, or methanol. It is driven by a 3/8in female hex from the camshaft or a dry-sump oil pump, or remotely by a cable drive. A high-efficiency Gerotor pumping mechanism sits in a Type III hard-anodized body CNC-machined from 6061 T6 aircraft aluminum. EFI applications require a high-flow bypass regulator.
