Identifying Brake Line

[JEvans22]

Which of the two hard brake lines off the master cylinder feed the front brakes? I’m installing a Willwood master cylinder and I’m not sure which line to hook up to the primary port. Thanks

Depends on if you had a PM or Vacuum brake master cylinder.
If your switching over from a Vacuum master, the front brake line connects to Wildwood front port.
Believe It's the rear brake line on a PM master that connects to Wilwood front.

The line that’s a smaller diameter feeds the front brakes and is what I attached to the primary port on the Wilwood. I swapped over from a powermaster so that line had to be persuaded to the front.
