Fuel delivery unit, fuel delivery system and vehicle

A fuel delivery unit (2) for use within a fuel tank of a vehicle, having:

• a surge tank (4) arranged on a wall of the fuel tank, wherein a fuel pump for delivering a liquid fuel from the surge tank (4) is arranged in the surge tank (4),
• a flange (6) arranged in an opening of the fuel tank,
• at least one support (8), arranged between the surge tank (4) and the flange (6),
• a flexible fuel line, configured as a feed line (10) and extending from a region of the surge tank (4) to a connector stub (12) on the flange (6),
• a wiring harness (18), which extends from the fuel pump to the flange (6),
• at least one flange-side holder (24), configured to form a first force application point for fixing the wiring harness (18) on the flange side, and
• at least one surge tank-side holder (26, 28), which is on the surge tank side and is configured to form a second force application point for fixing the wiring harness (18) on the surge tank side,
• wherein, the wiring harness (18), the at least one flange-side holder and the at least one surge tank-side holder (24, 26, 28) together form a force absorber configured to protect the feed line (10) and the connector stub (12) during a vehicle impact, wherein the wiring harness length between the at least one flange-side holder (24) and the at least one surge tank-side holder (26, 28) is shorter than the length of the feed line (10), such that, during the vehicle impact, as a result of which the surge tank (4) and the flange (6) move away from one another, the wiring harness length between the at least one flange-side holder (24) and the at least one surge tank-side holder (26, 28) is subjected to a tensile load so as to absorb kinetic energy acting on the fuel delivery unit (2) and thereby dissipate the kinetic energy, without the feed line (10), or the connector stub (12) to which it is connected, breaking off at the flange (6).
