Abstract

The invention pertains to a fuel system for internal combustion engines in which the unburned, heated fuel which is permitted to flow back to the tank from the fuel metering assembly is deaerated via an apparatus in order to prevent gases from re-entering the fuel supply pump when the fuel is reinduced thereto. By the inclusion of a jet pump between the fuel return line and the induction line, the degree of efficiency of the fuel supply pump is substantially increased.
