Fuel system started

I started the fuel system by making the TCW fitting spacers actually fit against the wing root fairing support - by trimming that support down to the hole edge, and then trimming the spacer to fit:

For the other spacers, Vans provided 6 of them, so I had to make another 2 (by just copying one of the 6), then I deburred and primed all of them:

I drilled the firewall fuel return hole:

I also received the super-nice-looking hose kit from Aircraft Specialty, with the integral firesleeves for the FWF portion:

I then installed all the cabin hoses that didn't require having the EFII system (which I'm still waiting for along with the engine itself):

Hoses installed under the seat

Valve with tightened fittings and (untightened) hoses

Valve with bracket center attached for installation

Actually attaching and torquing the hoses was actually a bit of work, given I had skipped ahead and done most of section 39 before - this would've been much easier without the pushrod in the way:

There was one small clearance issue, where I had to make sure to tighten a hose out of the way of the pushrod bolt/nut, but I'm not sure if this is a real issue after the elevators are attached, or if it just never moves this far forward:

Clearance between the elevator pushrod bolt/but and the left fuel supply hose

The rest of this section will involve installing the fuel pump hoses in the tunnel, and the fuel valve handle onto the center console.

Time lapse:

Total fuel system time: 7.8h
