Installed the F-8105 brake lines that connect the master cylinders to the parking brake valve. I also final-torqued the brake fluid reservoirs to the master cylinders using Fuel Lube. I spent quite a bit of time trying to come up with a usable location for a parking brake valve. It's not easy in an RV-8 -- there's just not much room. Still not sure where to put it where it will be relatively easy to plumb, and won't be in the way.
Next, I installed the fuselage bulkhead fittings for the fuel vent lines. Because I'm using relatively stiff teflon-coated rubber lines instead of stock aluminum tubing, I reversed the bulkhead fitting so the 45-degree section was inside the gear tower. That made it easier to attach the lines, and will provide strain relief.
Finally, I installed the fuel vent lines themselves. This is SO much easier than bending aluminum tubes up inside the tight confines of the gear tower... I can't believe anyone would ever subject themselves to the hassle. I'll secure the loop with an Adel clamp at the top of the gear tower.
