The fuel line is leaking at the carburetor.
A fuel leak can be a serious concern for your Corvette. One thing I can quickly recommend is to not use teflon tape. The fuel line fitting on your Corvette’s engine is designed to seal without it. Now there are a few things that can cause the fuel line at the carburetor to leak. These include reasons such as: a clogged fuel filter, which is causing unnecessary pressure; the fuel line was disconnected and secured improperly; or rust/debris is present and may be preventing a proper seal. Due to a fuel leak being a serious safety issue, I highly recommend enlisting the assistance of a certified mechanic to help diagnose your fuel leak as soon as possible to get you back on the road safely.
