Checked torque on all section 28 fuel line fittings, set ¼” to 60 inch pounds and 3/8” to 115 inch pounds per torques shown in Section 5 for aluminum tubing. Setup supply and return lines to allow total system to be pressurized at one time. Pressurized to ~ 5 psig and then used Snoop to leak check system fittings. Found two AN connections from tube to fitting with small leaks. Was able to disassemble, check and reinstall and confirmed leak free. No further detectable leaks. Pressurized to ~ 2 psig and held system for 2 hours with no pressure loss. Applied torque seal to all AN fittings in the fuel system.
