Abstract
A fuel-conveying system includes: a primary fuel pump, configured to supply fuel to an internal combustion engine of a vehicle, at a fuel pressure; a suction jet pump configured to convey fuel from a first region of a fuel tank of the vehicle to a second region of the fuel tank, the at least one suction jet pump having a nozzle; and a secondary fuel pump, decoupled from the primary fuel pump and configured to: supply, as required, the suction jet pump with a fuel jet, and set, independently of the primary fuel pump, a pressure of the fuel jet before the nozzle of the suction jet pump.

A fuel-conveying system for use in a vehicle having an internal combustion engine and a fuel tank (4) having a first region (4a) and a second region (4b), the fuel-conveying system comprising:
- at least one primary fuel pump (10), configured to supply fuel to the internal combustion engine, at a fuel pressure;
- at least one suction jet pump (14, 16) configured to convey the fuel from the first region (4a) of the fuel tank (4) to the second region (4b) of the fuel tank (4), the at least one suction jet pump (14, 16) having a nozzle (15, 17);
- and
- at least one secondary fuel pump (12), decoupled from the at least one primary fuel pump (10) and configured to:
- supply, as required, the at least one suction jet pump (14, 16) with a fuel jet, and
- set, independently of the at least one primary fuel pump (10), a pressure of the fuel jet before the nozzle (15, 17) of the at least one suction jet pump (14, 16).
The vehicle having the fuel tank as claimed in claim 13.
