Fuel line replacement

New guy here,
been lurking for awhile though. I am doing my first restore on a 72 stingray 454 I have been working on for about a month. Made tons of progress so far it seems though that the brake lines and fuel lines have got to go.
My question is do I have any other options other then lifting up the body away from the frame? Has anyone used plastic lines like Dorman? Life would be a lot easier, I’m not trying to win trophies but still don’t want to disgrace the corvette logo. If I have to lift it I will.
Thanks for the help

I have a few friends that have done a very limited lift - about a foot - to do such repairs on other GM cars such as Chevelles. I think you can replace the lines without a body lift if you are willing to accept a junction.

If you go all in and remove the body, and you have the time and money to really do it, it's a blast.

Good Luck with your adventure and be safe.

Can you tell us more about the flexible fuel line. Such as a brand, size, and maybe a part number?

Thanks,
John

This a question that is hard for me to answer simply because I went all in and removed the body on my car. If you Google "How to replace fuel lines on a 1972 C3 Corvette" you'll start the ball rolling. Here are a couple of opinions and such. As far as "flexible line" search Holley.com for information and parts (Earls). Also how have you guys determined the fuel or brake lines need to be replaced ?

I have a 502 1972 corvette that I replaced the line. I did it in one piece. I used a 3/8 aluminum line and just fed it thru the way the original went thru. Did it in one piece and without lifting the body.

decided to put the car back in stock form, and on adding the fuel return line (off the GF-45 fuel filter) I traced the metal line back to the "termination" (a crimped line done by Bubba). I was thinking of lifting the body off the frame as next Winter's
project so I could replace all the lines and POR-15 the top of the frame rails...
