I was wondering if someone could please give me the torque setting for the AN818-4D and the AN924-4D fittings on page 18-6 for the return fuel line fittings.
According to pg 9-19 in the FAA AC4313-1B Table 9-2 Tube data, the torque setting for this 1/4" tubing is between 50 (min) and 65 (max) Inch/Ibs. I assume these values are for the 5052 tubing found on certified aircraft. I can't find torque values for the softer tubing. Before I got to the min (50 Inch/Ibs) it felt too tight so I backed off.
Thanks in advance!
