Is there a document or web page(s) that describes how to cut fuel line tubing so that once the bends and flares are made the ends line up and the length is correct?
For example:
I have to create an L-shaped fuel tube to go from the bottom of an Andair fuel selector to a pre-existing fuel line with an AN fitting. I can't use the one that exists because I'm moving the selector forward. So after flaring the selector end and putting in the 90 degree bend, I need to cut the tube to length so that AFTER flaring, it fits snugly against the existing AN fitting.
So I need to know how much to allow for the flare when I cut the tubing.
I realize a lot of this comes down to practice. But I've found that there is often a lot of lore and help that can be absorbed before starting. I've been through the chapter on Fluid Lines and Fittings in the Aviation Maintenance Technician Handbook but there wasn't much there. Also reviewed Section 5.
Thanks!
