Tom Webster stopped by this afternoon to assist me in troubleshooting a leak in one of my fuel tanks. We thought we found it. The manometer was static for a couple hours, then it started to drop.
I forgot to write down the temperature, so I taped up the fuel cap again. I didn't get it quite flat and smooth when Tom was here. I started over again. The temperature hasn't change, but the manometer did drop about a 1/2", so I suspect there is still a leak someplace. We'll have to see in the morning.
