If you have an older Corvette that hasn't been completely restored, one fault you may notice is a smell of gasoline, especially around the rear end of the car. That's because Chevy used rubber fuel lines to connect the gas tank with the steel fuel lines that run up to the front of the car. These lines decay over time and if they haven't been replaced, they're at least 30 years old now!
I recently finished refreshing the leaky fuel lines on my 1977 project Corvette, and I documented the procedure for you. The thing to remember, though, is that while the general process is the same from the C1 to the C4 eras (1953-1996), there are model year changes and differences between the coupes, convertibles, and different tank sizes and engines - you get the idea. So use this how-to article as a good primer on the process, but rely on the service manual for your year and model of Corvette for best results.
