Abstract

An arrangement for pumping fuel out of a supply tank to an internal combustion engine having an electrically driven pumping unit which is disposed in a ram pot inserted into the supply tank. The ram pot is filled with fuel from the tank by means of a jet pump provided on its bottom; the intake opening of the jet pump is preceded by a filter that is formed by at least one ring of teeth axially protruding from the bottom of the ram pot, which enclose an intake chamber into which the intake opening of the jet pump protrudes.
