Did it leak before you replaced the carburetor? I would first get a new ferrule/olive that fits your existing line diameter, cut off the old ferrule, add the large nut and then the new ferrule, tighten and check. You can buy new steel or nickel/copper line and bend it to shape or pay someone to do it for you, if it needs replacing.
A ferrule is a barrel shaped sleeve that slips over the tube for compression fittings. Sometimes called an olive. When the compression nut is tightened, the ferrule compresses and seals onto the tube as well as sealing into the fitting that the nut is screwed onto. Once used, the ferrule is squeezed onto the tube and cannot be removed but the joint can be used over and over many times. However, all the components in that joint pictured just look plumb wore out. New tube, nut and ferrule should take care of it.
Stock tube and fitting size is 8mm but 5/16 is so close it works well. The nuts are the big deal as they must match the carb fitting. Stock nuts with 5/16 tube and a 5/16 ferrules have always worked fine for me with no leaks on the carb and fuel pumps.
You can get tubing in aluminized steel, stainless and cupronickel (copper/nickel). Cupronickel is easier to bend than the others. A lot of suppliers market 8mm and 5/16 tube as the same.
Here's a ferrule.

Nut:
Nut Union - Toyota (90402-13041) about $6.21 list at your local dealer
Ferrule (olive in Toyota lingo) - Olive - Toyota (96395-71400) about $4.22 list at your local dealer, or identical to the picture from @Steamer , above.
The tubing is available at auto parts stores. I'd find out if the store offers free rental of a tubing bender and tubing cutter so you can fabricate yourself. You don't want to kink the tubing while bending it, so the tubing benders are the best way to avoid kinks.
