I tried many different methods to fix a similar issue. After everything kept failing what I had that worked the longed was the nylon lines that they sell at autozone ad you heat up and press onto the babes fittings. But that didnt last too long either. I ends up using fuel injection rated rubber fuel line and put that onto the barbed fittings and used 2 hose clamps per connection. Basically both hose clamps butted up to each other. I had my lines like that for years until I switched to braided lines from the gas tank forward.

I also used efi rubber fuel line with hose clamps , it's been 3 or 4 years and so far no problem.

 

I bought new Nylon Line from Ron Morris Performance, dip it it boiling water and slip it in place over the barbs.

Get the nylon hose at Autozone. I converted my 85 to Holley TBI and used the nylon hose and nylon style fittings to convert an EFI tank to connect to my carb fuel lines. One tip...I had ZERO luck with the whole boiling them lines and pressing them onto the barbs. I couldn't get it halfway. I found a super easy way to do it, without having to spend the money on the proper tool.

Get a 45 degree brake line flare tool. Just get the clamp part that holds the steel line. Get a caulk gun. BUT, get one that is open on both sides. Most of the cheap ones are half closed and you slip the caulk in, but I had some that basically just have 2 straps...one on each side of the caulk tube. No caulk in the caulk gun, clamp the nylon line in the brake line clamp...just short of how long the barbs are. It will take some wrangling, but get the end of the caulk gun lined up with the fitting and just press it in.
Once you do it, it works super easy. I can put a barbed fitting in nylon in about 30 seconds and it goes all the way flush every time. Also, it may seem convoluted and difficult, but it actually pretty easy. When I was mounting a factory style fuel filter I somehow nicked the line and put a pin hole in it. With the car on jackstands, I crawled under with my contraption, lay on my back and cut the line off and put a new fitting in, in about 5 minutes.

 

this sounds interesting... any chance you have pics of this apparatus??? i need a visual!

 

I took the chrome upper lines right off used braided with fittings to go straight from rails down to existing hard lines under pass door with an style compress fitting cost was $120

Now when money is right I can remove all stock lines and run braided the length of car
Worked mint for me screw that nylon bs
