I ran the long fuel line that goes from the outlet of the pump up to the firewall:
I used a steel fitting through the firewall, since a flexible hose will connect to it on the forward side. I've decided to use only steel fittings on anything that carries important fluids and will see substantial vibration.
What a mess. The electric pump plumbing is insane-looking but it all fits. I did have to remake the line on the port side that feeds fuel into the selector valve, in order to clear some other plumbing. One other thing to note is that it's going to be very tricky to get wires routed between all this stuff and through the pre-drilled wiring holes in the spar (just barely visible behind the spaghetti).
Here's a view of the other side. Everything fits together, amazingly enough.
A view looking aft. None of this is permanently put together yet – I'm planning to take it all apart and blow the crud out of the lines before I tighten it all down for good.
