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..

Thanks for the info, I didn't realize tubing is sized by the OD. That is good to know.
5/16" worked. I've got the new line bent up and in place. I did also learn that I need to work on my tubing bending skills

3/8" fuel pumps flow more gas than 5/16 ones

Good to know. I think 5/16" will be more than enough for the 250 currently living in the truck
Thanks again for the info!
