FLK-38 3/8" Nylon Fuel Line Repair Kit, 25FT Fuel Tubing Connector Kit for Gasoline and Diesel Systems, 23PCS Set with Quick Disconnect Fittings and Compression Unions, High-Pressure Nylon 12

Automotive Fuel System Restoration Matrix: Application: Gasoline Delivery, Diesel Return, and Evaporative (EVAP) Systems Tubing Specification: 3/8" ID (10mm) Nylon 12 High-Pressure Tubing Working Temperature Range: -40°F to 240°F (-40°C to 115°C) Maximum Operational Pressure: 2.8Mpa (400 PSI)Included Hardware Components (23-Piece Total): - 1 x 25ft 3/8" Nylon Fuel Tubing - 2 x 90° 3/8" Quick Disconnect Fittings - 2 x Straight 3/8" Quick Disconnect Fittings - 2 x Nylon-to-Steel Compression Unions - 2 x Steel-to-Nylon Adaptors & 10 x Heavy-Duty Retention ClampsProfessional Installation Advisory: Nylon fuel lines require specific thermal or mechanical expansion for fitting insertion. To ensure a secure integration, it is recommended to use a professional fuel line press tool. Ensure all cuts are square and free of burrs. Do not expose tubing to open flames during the heating process. This kit is designed for under-body fuel routing and is not intended for high-temperature exhaust proximity.Compliance & Safety Standards: Treated for environmental exposure endurance and tested for salt spray resistance. This product restores factory performance parameters and addresses excessive mechanical wear in the fuel delivery path. Always perform a static pressure test after installation and before engine startup.
