Into the belly of the beast! I installed my "red cube" fuel tranducer that measures fuel pressure and flow. I may end up moving it between the fuel pump and the carburator but I really had a tough time finding a place to do it. So after MUCH dithering, I decided to try it much further upstream... I'll see how it goes. I also got the fuel line plumbed to the bottom of the collector tank all the way to the carb, and the vent and supply lines connected at the top of the tank.
You can see the supply and crossover line in the baggage compartment hanging on a zip tie. Once the wings are installed, the lines will be connected to the wing tank and routed behind the beam and out of sight.
