Reinstalled right tank, crossfeed fuel line and fuel vent lines. Ran oil vent line hose. Calibrated Kanardia fuel gauges. Did hang test to determine CG without fuel, then with fuel. Installed updated brackets for landing light and anodized throttle lever. Cleaned up and secured wires for strobe lights. Also installed anodized mounting bracket for transponder antenna. Took it outside for some GPS tests. Noticed we weren't getting GPS info to the transponder so will need to troubleshoot that further.
