Submersible PTFE Fuel Ta nk Tubing 5/16in x 12in

The VIBRANT PERFORMANCE Submersible PTFE Fuel Tank Tubing 5/16" x 12" (VIB18055) is a specialized in-tank fuel line engineered for applications requiring superior chemical resistance and reliability in submersed fuel system environments. This flexible tubing delivers the dependable performance fuel system builders and custom builders demand when constructing or upgrading high-performance fuel delivery systems that contact gasoline directly inside the tank.

The 5/16-inch inner diameter accommodates mid-range fuel flow requirements common in street performance and racing applications, while the 12-inch length provides flexibility for installation routing within confined tank spaces. PTFE (polytetrafluoroethylene) construction resists gasoline degradation, ethanol blends, and methanol—critical advantages over standard rubber lines that degrade when continuously exposed to fuel solvents. The white exterior aids system visibility during installation and inspection. At just 0.1 lbs, this tubing adds negligible weight while delivering proven durability in automotive and powersports fuel systems.

This in-tank fuel line suits builders upgrading carbureted engines, EFI fuel systems, or vintage restorations where OEM fuel-system materials have failed or where ethanol fuel compatibility is a concern. The submersible rating confirms suitability for direct tank immersion, making it the correct choice for fuel pickup tube extensions, return lines, and crossover applications. VIBRANT PERFORMANCE delivers OEM-quality tubing used by professional shops and serious enthusiasts building fuel systems that must withstand real-world durability demands.
