I ran my brake lines around the sides of the fuselage rather than through the holes and down the center console. Seems to make much more sense to me and easier to do also.
I also did the vent lines differently. Ran them straight forward through the bulkhead to the front corners just behind the firewall, then up the corner and back down again. I found this was easier than the planned route. BUT don't skip the up-and-down-in-the-corner part, otherwise you will likely find fuel bleeding out the lines onto the ground. Also make sure there is clearance for any rivets, bolts, etc. that you need to work into that corner.
