Front brake line 68 Barracuda

My front brake line is pieced in two with a union, It runs from the proportion valve to the fire wall across to the pass side down to the wheel does a loop by the right front wheel and is broke at hose connection.
My Question is this the correct location? Without the two piece and the loop. I am putting one piece with no union.
anyone have one or do i have to buy a full set? thx johnnycuda still working on the carb.
This is unclear.

However, the brake line from the proportioning valve to the RF flex hose area should be one piece
