Tin Bundy Weld Tubing – OE-Authentic Fuel Line Construction
TBW was original equipment on the Corvette. Tin Bundy Weld is the manufacturing technique used to form the fuel line tubing. This brazing process results in improved resistance to internal rust, reduced brittleness, and longer service life—exactly what GM used to deliver consistent fuel flow and durability. These OE-style lines are true to factory specs and finish.
Because Details Matter
Your fuel pump to carburetor lines should do more than just connect fittings. They should follow the correct bends, use the right materials, and look like the ones your Corvette had the day it rolled out of St. Louis. This 3-piece TBW steel tubing set does exactly that—down to the fitting angles, line routing, and flare design.
