Conditions needing inspection
- Raw fuel odor or wetness appears along a line or connection.
- Underbody damage, corrosion, or abrasion affects a fuel-carrying component.
Identify the actual source
A leak may originate at a fitting, seal, rail, or nearby component rather than the line body. Routing and support problems can allow repeated contact and wear. The repair scope should account for neighboring damage and the line's pressure rating, material, and vehicle-specific connection requirements.
What replacement generally includes
The affected section and access requirements are established after the system is made safe using the proper procedure. Correct replacement lines and required seals or one-time-use connections are fitted. Routing, support clips, and clearance from heat and moving parts are checked. The completed circuit is inspected for leakage under the appropriate operating conditions.
Arrange service safely
Do not keep driving with suspected fuel leakage or attempt to seal a pressurized line externally. Park in a safe location, shut down, and seek professional help. Tell D&S where the odor or wetness appeared and whether an impact or recent repair preceded it so the inspection can focus on the relevant area.
