Min. tube bending radius

Hi. I just installed fuel tube from Andair selector to Facet pump. I managed to do the bend beside the fuel pump, but I'm not sure it is OK. Where can I find minimum bend diameters for a given aluminium gauge?
Thanks.

Tubing Data

See Table 9-2, page 9-19 in Advisory Circular (AC) 43.13-1B, Change 1 (ISBN 0-89100-306-1).

Although the chapter covers hydraulic systems, the table should provide the information you need.

This table also provides torque minimums and maximums for AN-818 tubing nuts.

Another reference is the "Standard Aircraft Handbook" by Larry Reithmaier (ISBN 0-07-134836-0). This book also has a table (page 183) for tubing bends and torques...bends are the same as the above reference but torque values are different; if in doubt, I'd go with the AC.

Regards,
Mike

Thanks Mike

Thanks Mike,
I was also looking for this information.

Thank-you. I will look there.

90 deg fitting

You can get a 90 deg steel fitting for the Facet pump. I don't have the exact part number handy but I got mine from Spruce.
