I'm employing a used Kohler-type primer pump off of an O-540 Ag-Plane; I tapped the fuel inlet from just above the fuel pressure sensor and ran fixed line until close to the pump, where flex line was used because of the panel's ability to tilt forward for maintenance. A flex line was used to the firewall for the outflow. (The static port switch was cockeyed for the photo, as it hadn't been tighted down yet).
