Every piece of tubing cut should be deburred and be blown out with compressed air. I leave a countersink bit in my drill press just for this. After doing so then proceed to the flaring steps. The blowing out of the tube also eliminate any thing else that may be in there, dust, debris, dead bugs etc. https://www.tandmautomotive-omaha.com

Its about the cheapest way to do it without buying tools. The compression sleeve costs less than 50 cents.

Not familiar with compression fittings, what exactly is needed? Sorry for the basic question.

I would buy an inexpensive double flaring tool and do the first step as suggested. You can practice on a piece of tubing which is cheap. What size line?? 1/4 and 3/8 compression fittings are easy to come by. 5/16 could be a bit more difficult as it is less common/ https://www.tandmautomotive-omaha.com

I would say the loose ones were not tightened enough to seat them. A person could use a film of Loctite under the sleeve if warranted.

Agreed on the tightening, the brass is also softer that steel which compounds the issue. If using loctite make sure the type being used is fuel resistant. I've actually found a few on rusted brake lines 😲 and was surprised they held as they are not rated for that kind of pressure https://www.tandmautomotive-omaha.com
