I'm having trouble with the fuel line that connects my airflow pump to the firewall. The problem is that the run is short and has a zig-zag (technical term
If I try and bend it to shape before flaring the straight sections are too short to fit in the flaring tool. So instead i've been cutting the right length, flaring both ends with fittings and then trying to bend it into a Z. Every time I do this, and I've done it four times, the bends collapse a little bit and look squashed. I have a tubing bender but I can't fit the tube into it because the ends are in place.
What am I missing here? I assume the tubing can't be at all collapsed which I think is right and if I try and uncollapse it with seamers it just makes it square. I made all the rest of the hard lines so far with no problem but this little one is driving me nuts.
