Going to replace my gas line, '46, wondering if I should use, plain steel, stainless steel or copper, not a show car, weather permitting its a daily driver, just want something that wont give me trouble for long time.

The stock fuel lines are still being made, and are available from many suppliers. The best for non stock would be Cunifer, pricy but best. Stainless steel is good but hard to work with. Never use copper or plain steel.

Just to add to what Alan has said. You want to use copper plated steel which is what the original gas lines were. Plain steel will rust and plain copper will develop fatigue cracks.The copper plated steel is available from all the usual suppliers at a reasonable cost.

I just replaced the gas line in my 1939. I purchased the copper plated steel line from Roy Nacewicz. It comes in 36-inch coils and includes the end fittings. It worked out well.

About 10 years ago I replaced my fuel line (tank to firewall) with copper (so easy to work with). Firmly anchored it's whole route. Lately there have been posts about copper fatiguing. So should I replace it? Does anyone have a first hand experience with copper lines fatiguing? Thanks John

First hand, yes. I worked in an industry that used copper lines for vacuum. I had made new lines and stashed them for future use, then forgot them for 10 years. I was very surprised to find that they had stiffened very hard, as opposed to the soft malleable copper that they had originally been. Further, copper lines in service would harden and rupture if used more than 3 times, but then, high pressure/temperature would be expected to shorten the life of any tubing.

The line from Nacewicz comes in a 25' length and is coiled in 36" rings. It is the best fuel line to use. Some of the other vendors supply a line that is copper plated on the outside only.

Use the new copper/nickel fuel lines. They never rust inside or out,even using ethanol. Also,you can bend them with your hands and they don't kink,and being made as gas lines they are seamless so you don't have to worry about them ever splitting from vibrations. 5/16th is right at 30 bucks for 25 feet,which is plenty to do your car. You can buy it at Car Quest,MAPA,O'Reilly auto parts,and pretty much any other auto parts store. You can even order it from Amazon if you want. Just do a search for brake lines. I used it on my 51 coupe and am very glad I did. No more worries about rust inside the lines that I can't see,or rust flakes getting past the filter. While you are at it,make sure you replace all your rubber gas lines and any plastic inline gas filters with new ones that are rated to stand up to ethanol.

Is this the stuff you're talking about? http://www.surrauto.com/documents/Ultrabend-Brake-Line-Tubing.pdf I've got to replace a fuel line and had this suggested on the Ford Barn.

Not saying it isn't cupronickel, but do you see it stated anywhere what alloy it is? Seems fishy to me that it wouldn't be proud of naming it.
