I'm in the process of restoring Mom and Dad's 1974 Vette and I ran into something I could use some help with:

The master mechanic I hired to give it the full looksee found the gas lines from the tank to the front are showing signs of rot (lines are damp and shouldn't be). I need to hire him out to do this as I'm not messing with this part of the project.

He's cool doing the work, but he needs me to find him the parts. The sites you all mentioned are great for parts, but I'm wondering anyone has a link to a full kit for this kind of thing (lines, connectors, clips hardware etc.) or wouldn't mind leaving me links to the parts I'll need to buy for this whole part of the project. I just don't want him to start up and then run into a situation where he's missing something that I forgot to grab.

 

Thanks in advance!

I'm not personally aware of any of the aftermarket vendors that handle kits like you need. But what you probably need most of all is a Corvette Assembly Manual which you can get from some of the aftermarket Corvette vendors.  It's basically a pictorial step by step manual on building the Corvette. It includes part numbers and assembly instructions.

I think you will have to lift the body up 6" or so or buy a pre-bent fuel line and cut it into 2 or 3 sections.

Found this thread on Digital Corvettes that should help.

I run nickel copper lines in everything I do.  There isn't a "kit" but it's easy enough to bend by hand to get the perfect fit.

Have you inquired at Bairs Corvette parts? They have preformed lines. They provided mine for my project. They also are sponsors for our site. They cater to our needs.

I was told many years ago by someone in the auto industry that the reason they didn't use copper lines was because they were subject to embrittlement cracking.

When I replaced the carb with EFI on my '75 coupe, I used PVF coated steel lines -- hope to keep them from rusting.  I bought mine on Amazon.

Personally, I would not use copper. The seams are not real pressure tested. AND, are not legal or will pass inspection here.

Years ago I had to lift the body off my 73. I am in Michigan so the supplier I use is Vette Products of Michigan.

Vetteproducts.net

i bought the stainless steel fuel and brake line kits at the time but I would think the standard lines would last many years on these old cars. 
They make the lines there and use the GM design so they look and fit just like the original lines.

again, this was quite a few years ago but I never have any issues with this company
