Purpose and Function in the Fuel System

The presented fuel tank hose operates within the fuel supply system, responsible for safely conducting fuel between the tank and further installation elements. The appropriately selected nominal diameter of 18x23 mm allows for:

• maintaining the correct fuel flow cross-section under typical operating conditions,
• limiting pressure drops on the section between the tank and subsequent components,
• ensuring stable injector system operation with standard engine parameters.

Proper hose fitment for a specific body version and fuel system is crucial for safety, making this element particularly important for repairs related to leaks or system upgrades.

BMW Compatibility and Reference Numbers

The hose is designed as a dedicated part for selected BMW E-series models, facilitating installation in place of the factory component without modifications. The product has an assigned OEM part number and associated interchangeable numbers, allowing for precise identification of compatibility with a specific vehicle configuration. This enables systematic component selection for the existing system, minimizing the risk of ordering errors.

To further leverage manufacturer markings, it is advisable to consult the practical tips in the guide on verifying components by factory numbers – the article Risk-Free Online Parts Shopping – 5 Proven Ways to Verify Component Compatibility by OEM Numbers and Paint Codes discusses these in detail.

Performance Characteristics and Installation

As a component from the Other Injector System Parts group, the fuel tank hose acts as a connector between the tank and the rest of the installation. When selecting and installing, pay attention to several technical aspects:

• proper hose routing in original clips and guides,
• checking the condition of connectors and clamps,
• maintaining the correct bending radius to avoid restricting fuel flow.

The product comes from the BMW segment, which promotes maintaining factory conduit routing geometry and compatibility with standard fuel system components. Its used condition allows for economical repair while preserving the original construction.

Application in Service and Diagnostics

Replacement of the fuel tank hose is recommended when symptoms such as fuel odor around the rear of the vehicle, signs of leaks, or visible mechanical damage to the hose appear. In service practice, this component is often replaced during:

• repairs after collisions in the rear body area,
• injector system upgrades or overhauls,
• corrosion and leak removal around the fuel tank.

Selecting the correct component according to manufacturer markings facilitates integration with the existing installation and reduces workshop time, which is important for both private users and professional service centers.
