1978-1982 C3 Fuel Line TBW Fuel Tank to Fuel Pump - OE Style
1978–1982 C3 TBW Fuel Line – Tank to Fuel Pump – OE-Style Tubing
If your 1978–1982 Corvette still uses its original fuel line, there's a good chance it’s compromised from the inside out. Internal corrosion, ethanol breakdown, and external wear can cause flow restriction and fuel contamination. This reproduction Tin Bundy Weld (TBW) fuel line restores proper delivery from the fuel tank to the fuel pump, eliminating issues caused by brittle, kinked, or rusted-out factory tubing. Pre-bent to factory specs and built with OE-style brazed construction, it’s the smart fix for late C3 reliability and restoration correctness.

Tech Notes
Tin Bundy Weld tubing was the original GM process used on late C3 fuel and brake lines. Its brazed construction provides smoother internal surfaces, better corrosion resistance, and improved flexibility over standard welded tubing—perfect for restorations that need to last.
Because Details Matter
From frame rails to firewall, your fuel delivery system needs to function and look the part. This TBW line provides the reliability of modern materials with the exact fit of factory routing—because even what's underneath should be done right.
