I need to replace it, but I don’t know what size the line is or what size the fittings are. Are they double flared?
Any suggestions on what to use to replace it would be appreciated!

For future information, all tubing (we're not talking pipe here) is measured on the O.D. Most 6 cylinder I6 equipped '67 - '72 GM pickups came equipped with 5/16" fuel delivery tubing.. Your truck is over 55 years old. Anything can happen, changed, modified, and/or hacked.. Before buying up a bunch of wrong size tubing, measure what you have left. Then you'll be sure of what you have...
To answer your flare question.. Yes, fuel line is double flared.. Pre-flared brake line is a good replacement for fuel lines. They can be joined together by using a brass Flare union, and bent to shape/fit using a common "hen house" tubing bender..
