I got the other fuel vent line made up and installed the other day, but I forgot to take a picture of it. This morning I put all the adel clamps on both vent lines, so you get a picture of the second vent line now.
Then I installed the brake reservoir on the firewall, in the location called out in the plans. I used the unibit to enlarge the pilot holes I drilled in the stainless. It took a bit of measuring to figure out exactly where to drill, but it turned out great. For those of you playing along at home, the bolt holes are exactly 2" apart, and the pass-through hole for the fluid fitting is 1/2" diameter, 1 3/8" down from the centerline of the bolt holes.
I started playing around with the brake lines, but I am really having doubts about the use of plastic tubing here. Even though it worked fine on my other RV, it just seems cheesy. I may wind up using more robust braided steel lines (example here) rather than the plastic. Not quite sure what lengths of hose I'd need to do that, though.
