Heck if the tube is so thick it wont double bend then it should be strong enough for duty.
On the cracking problem, vertical or horizontal, it is something I have not encounterned on new stock. Maybe with a microscope the tube may crack at the fold end but there is no fluid there to concern.
I scanned this instruction chart. Try chamfering the tube end before bending it, that should relieve some stress.

I have never had a problem with the garden varity 1/4 inch tubing cracking when double flairing it. Possibly the tubing you are using is of the wrong alloy.
I cannot find in the Auburn parts book pages 62 & 63 (carbreter & fuel pump) any reference to a part number for a comperssion fitting. It does make reference to the fitting and nut inverted flair for both the carburetor and fuel pump. What am I missing?
The bitterness of poor quality remains long after the sweetness of low price is forgotten.

If you are building fuel lines, use sleeves and compression fittings, much less prone to leaking volatile fumes at low pressure.
Generally, flares, brakes, compression fuel.
Compression fittings and 5/16 copper chromed lines look detailed in the engine compartment and are very flameproof.
Question,
What is the longest word in the English language?
---"Smiles"---
because there is a mile between the first and last letter.

When flairing the copper tubing be sure to aneal the flair it will seal much better. Copper tends to work harden. There is also 1/4 inch copper tubing available that is rated to 3200 psi for the brake lines.
Actually I was referring to the fuel lines not brake lines
Thanks for the info everybody, guess I'll replace with copper
