RE: Tank mount in older planes
The vent line on a gas tank can not just run to the firewall and be secured. During certain manuvers the fuel will run out the vent. The process of wrapping the line around the tank and looping to the back of the tank and then to the front makes it so that no mater the orientation of the plane fuel will always have to run up hill to get out the vent. In glow this is not an issue because the vent is connected to the exhaust which has pressure on it when running. I am looking for ways that guys have mounted their gasoline tanks in a plane that has a removable wing on the bottom.
