1968-1969 C3 327 Fuel Pump - Carb Lines TBW 350 HP Quadrajet 3 Pieces

Restores Fuel Delivery with OE-Style Tin Bundy Welded Steel Lines
Stock fuel pump to carburetor lines can rust internally, releasing metal debris into your fuel filter and compromising performance. This 3-piece reproduction line set solves the problem with accurately bent tubing that matches the factory routing for 1968–1969 L79 327/350HP and L46 350/350HP Corvettes equipped with the Quadrajet 4-barrel carburetor. Whether you're eliminating leaks or replacing unsightly kinked tubing, this kit restores fuel flow with factory-correct style and function.

OEM Fitment and Routing Accuracy
• Fits 1968–1969 small-block 327 and 350ci Corvettes (350HP) with Quadrajet
• Designed for L79 and L46 engine options
• Pre-bent steel tubing with double inverted flares and steel nuts
• Includes: fuel pump to filter line, filter to carburetor line, and fuel filter overflow return
• Matches OE size, shape, and location using original-style bends
• GF-432 fuel filter not included (sold separately)

Technical Notes
• Gas lines are OE-style steel with correct flaring and fittings
• Tubing is prebent to match original factory configuration
• Reducers may be present in your original system—check and transfer if needed
• Inspect carburetor inlet fitting before installation; a damaged or crushed fitting can prevent sealing
• Replaces worn or bent lines while maintaining correct fuel delivery volume and appearance

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.
