Abstract

A fuel fractionation device is provided for separating a low-boiling fuel fraction from a liquid fuel in an internal combustion engine, having a fuel tank which contains the liquid fuel and having a separator, to which an extracted fuel fraction mixture can be fed, and a reservoir to which the fuel fraction can be fed, and furthermore having a pump which extracts fuel vapor and air and has a pump drive. The pump and the pump drive are fixed in a housing and are accommodated removably in the fuel tank together with the separator and the reservoir, forming a structural unit.
