1975-1977 C3 Fuel Line Fuel Tank to Fuel Pump TBW - OE Style
1975–1977 C3 TBW Fuel Line – Tank to Fuel Pump – OE-Style Replacement
By the mid-1970s, GM’s focus on emissions and durability meant tighter routing and additional vapor recovery requirements in the Corvette’s fuel system. Unfortunately, that also means your original 1975–1977 Corvette fuel line is now decades old and highly prone to internal corrosion. Rust flakes, collapsed bends, and ethanol degradation can restrict flow and cause poor engine performance. This OE-style Tin Bundy Weld (TBW) replacement fuel line restores full fuel delivery from the tank to the fuel pump, while duplicating factory bends and material composition for an accurate restoration.
Features
• Correct for 1975–1977 C3 Corvettes
• Restores fuel delivery from fuel tank to mechanical fuel pump
• Tin Bundy Weld (TBW) construction for OE accuracy
• Resistant to rust, kinking, and ethanol-related breakdown
• Pre-bent to match original routing along frame and chassis
• Compatible with factory vapor recovery systems
• Ideal for show-quality or daily-driven restorations
Tech Notes
GM used TBW tubing on original 1975–1977 Corvettes. This brazed process results in smoother internal surfaces and better corrosion resistance than basic welded lines. If your fuel system includes vapor return lines, this tank-to-pump line integrates cleanly with those fittings.
Because Details Matter
Fuel delivery is too important to trust to rusty originals or universal tubing. This TBW line gives your C3 the correct look, proper fit, and dependable performance your restoration deserves—on the road or on the show field.
Don't forget the correct Corvette Brake and Fuel Line Clips!.
