Installed the eight 625-8 snap bushings for wiring through the holes in the center spar. Hopefully that will be enough room for all the wires going between the front and the back of the airplane.

Looked at plans and marked up with changes (-8 instead of -7 snap bushings, extra washers on landing gear bolts since I used slightly longer bolts to replace the ones that were too short, F-6116 cut in half and use of AN960-10L washers as spacers).

Test fit the fuel valve mounting plate and the fuel valve enclosure to see how the extra cover I made works in filling the gap between the two. Looked at the Van's valve and the Andair valve mounting. There are a lot of covers in the area and the assembly order matters. Also looked at brackets on front of the center spar to see how the brake and fuel lines run. I think I have to run tubing then bend and flare it and will not be able to remove the tubing without cutting it.

Will call Van's builder support tomorrow with the following questions:
- Fuel/brake lines - push through support brackets, bend and then flare?
- Location of holes in firewall for brake reservoir and fuel bulkhead fitting. Drill now or wait for engine?
- Type and material fitting for firewall fuel line?
- VA-107 brake reservoir and fitting doesn't work? Fitting too large?
