from interior doghouse thru floor
from cab to tank.
Btw, went to oreillys auto to find a hose that had the weird brake hard line size of 7/16 and axle hose size of 3/8 threads. The old guy behind the counter pulled a 8" thick book out and started typing numbers into the computer to see if he had them in stock.
About half way through the first page the mgr. came over, shook his head, and took the hose I had back. Two minutes later he came back with some hard brake line and 2 new fittings. The old guy was still typing.
All I had to do is bend the line to fit, put on the fittings, and flange it. Just need to bleed brakes.
