I ran alum & years later it spring a leak where it was rubbing on an Adel clamp that was missing a piece of rubber around the ID of the clamp. On my last one I used prefabbed lengths of parts house 3/8" straight line with the male inverted flare ends & joined them with an Edelman brass double female inverted flare fitting. Never again the stuff is too hard to bend. There's gotta be some softer steel

I'd never use aluminum; only advantages are weight and ease of forming and the weight is negligeable and mild steel isn't hard to form. disadvantages are aluminum is brittle and prone to stress cracks.....not something I'd want for a fuel line. Steel or SS Dave

Exactly. With todays gas, there will be problems with aluminum lines sooner than later too. For a street car it's much more dangerous than a race car.

If your aluminum is cracking, you are using the wrong aluminum or its installed wrong. You DO NOT double flare aluminum, you need specific radius bends for each specific line, Aircraft vibrate much more than most race cars, they have been using it for decades and no issues when done correctly. Tim

I am not sure it correct to compare an airplane to a car. No fuel corrosion issues, not sure hitting a pot hole/curb is the same as being buffeted, little road debris at 5,000 ft, most lines in a plane are enclosed, and weight is a bigger issue aloft, routine inspections are required in aircraft but cars are more install and worry about when there is problem, and not much reason to worry about a fender bender in the air. However the concept of properly installing a fuel line likely is valid for both.

The aluminum line I used was from Summit Racing. 37-degree single flair with AN Fittings and the AN tube sleves/nuts. It was fine for about five years, then got one crack near the flare at a bulkhead fitting at the engine compartment. May have been some flexing from the body that caused the problem? I may have needed a strain relied bend in the line to account for some body flexing?
In 3/8" I like the reproduction lines in stainless steel. Factory fit and look, and compatable with any fuel.
You experienced what we are warning about, aluminum will crack eventually. Will you catch it soon enough? Too much vibration in a street car and doesn't offer the protection you need in a crash.
The guys who say it's fine, I bet they don't drive there cars much. imo I'm still using the original steel 5/16 fuel line in my 74, do you think that would be the case if it was aluminum? I don't think it would last this long, electrolysis would have eat it by now.
