No issue with the factory line for me really, but when installing my map sensors, I needed more vacuum ports and the only practical, quick way to do it was make a new booster line with an inline tap.

Hard to see in the pic, and it's not current, but my map sensors are next to the resistor box, and the lines run to an inline tap on the brake booster line on the back of the manifold, then a check valve between the inline tap and booster itself.
Rather than tap into lines that are best left alone, this is an option for adding a port without pulling the manifold. Finesse required.
