I have been smelling gas lately. Just found the fuel line was spewing gas at the connection when i opened the hood. this part is discontinued for 1993 z28s. any ideas from anyone how this could be repaired?

 

You may want to move this to the right forum, this is the "Parts for Sale" forum.
To answer your question though, there are replacement fuel line assemblies out there for sale, new and used. Just look around in this room for "Parting out" posts.
