[Chevelle-List] Brake Line Question ??

[Misterbowtie66]

Morning All....
Question ?? Do the brake lines between the master cyclinder and prop valve have to have a loop in them or can they just be run from one to the other ?? Been to a few car shows and have seen them where they run from one to other with no loop. Ready to install now, please advise...thanks
