The mating steel line should to rust free to ensure a long lasting, leak free connection.I need to replace a section of hard line for fuel supply and return lines under the car due to rust. Is it acceptable to use compression fittings/ unions to join the new line with the existing line?
Some of the stuff you post is just something.keep a fire extinguisher handy
Indeed, it is much too difficult to double flare a steel fuel line.Some of the stuff you post is just something.
Why do it if you don't have to? I'm not a fan of double flaring "wet" lines-- I do it, but only when I have to. Fluid runs down my arms when I'm working on my back under the car... gross!Indeed, it is much too difficult to double flare a steel fuel line.
It might be “ok” on some old lady’s rusted out rear brake lines on her buick (after all, who cares about old ladies?) she’ll probably never press hard enough to rupture the “compression fittings”, and even if it fails, the dual master cylinder will still stop the car.Why do it if you don't have to?

A compression fitting also allows the line to be cut a few degrees off of square and still seals.
Yea my point exactly, fuel line rarely have more than 50 psi. Brake lines and hydraulic line way different story.Wait a minute, I thought we were talking about fuel lines? Brake lines, I flare and use metal coiled brake line.
Yep, DI and FI hold enough pressure to warrant a double flare, anything less is pure negligence.Wait a minute, I thought we were talking about fuel lines? Brake lines, I flare and use metal coiled brake line.
It's not ok on brake lines. It is ok on 60 psi fuel lines.It might be “ok” on some old lady’s rusted out rear brake lines on her buick (after all, who cares about old ladies?) she’ll probably never press hard enough to rupture the “compression fittings”, and even if it fails, the dual master cylinder will still stop the car.
Try that same trick on one of Astro14’s aeroplanes and you might find a different result lol
Oh, we use compression fittings on modern aircraft. We use them everywhere. However, they are NOTHING like hardware store fittings.Try that same trick on one of Astro14’s aeroplanes and you might find a different result lol
