Got to bring the "commotion lotion!" I added a fuel pump on the bottom of the firewall, the system is gravity feed from the wings, but I thought a boost pump would be a good idea if I ever need the last few gallons in the collector tank (I'm not sure what the pressure will be like with this custom install) since the carb takes gravity flow or fuel pump. I also installed the cutoff valve in the cockpit, but I'm not happy with the labeling... I followed the factory version, but I think I'll relabel it to something more intuitive. I also installed the carb temp probe in the throat of the venturi, this should give me the ability to monitor the threat of carb ice.
