Braided Stainless Steel Fuel Line

-
Does anyone sell 1/2" steel hardline that's easy to form?
Ni-Copp (nickel/copper alloy) is very durable, easier to form than steel, and MUCH easier to form than ss.
It's NOT cheap, and I don't know if it's made in 1/2.
Edit: 1/2 Ni-Copp is available, found a 25 foot coil, for $240
 
I've read lots of bad reviews on the nicopp line. Like it kinks badly and doesn't bend very well and collapses easily when you try to bend it. Does it take a special bender?
 
I use 1/2" .028" wall 4130 seamless steel or stainless steel tubing I buy from several tubing supply houses. Then I bend it with a Swagelok hand bender.

I've bent .058" wall 4130 seamless and .035" stainless steel by myself with that bender. Regular 1/2" .028"/ .035" wall DOM steel tubing would also be fine and a lot easier to bend.

I didn't realize you could get the 1/2" stainless hardline annealed. Does that mean this stuff is reasonably easy to form and flare?

1/2
I wonder how that would compare to something like this in terms of ease of use and durability?
Copper Nickel Fuel / Transmission Line Coil. 1/2

Nope, pretty easy to bend with a cheap bender.

The only downside to tubing is sizing. The tubing has a smaller ID than hose does.

Also, I never use hose clamps on fuel lines any more.

You can get flare nuts or whatever they call them and use AN fittings for connections.

Much cleaner and safer than hose clamps.
 
Yes, you can get copper/nickel in 1/2", I got mine at Summit, it was around $86. for 25 ft. $50. something for 3/8". Yes, I used AN flared nuts and sleeves on it for fittings. You do have to have an AN flaring tool, I have one, built an airplane. In difficult bend areas I used SS braided line or AN fittings. My new car is an old race car, so my fuel feed and return lines are routed a little differently, 1/2" and 3/8"", but all doable and doesn't look bad.
1/2" Feed line, # 8 AN
3/8" Return line, #6 AN. Yes this size through the fitting is close to 1/4".
Regular tubing bender
Having said all of this, if I had a normal car, I would just get it all from Inline tube or some other mfr. Think that we have lost the OP here! Sorry!
 
Aluminum fuel line is cheap, and it's easy to work with, but it's also really easy to screw up. Personally I would never use it. If you have invested good money in your car a fuel line out of aluminum is just not something I would do. Take the time and effort to run hard steel or stainless steel lines if you care about the future of your investment.

I'm a believer in using Cu-Ni lines. The stuff is easy to bend, easy to flare, easy to work with. And not very expensive. Pressure is not an issue for it. It doesn't rust. It seals well after you flare it. Because it's easy to work with, you can run it right up to where you need it and then go to a short(er) pieces of braided to get to the final spot.
 
Yes, even the 1/2" doesn't bend bad, but no really tight turns. I like it.

Thank you! How does it compare to say aluminum in terms of work hardening and splitting?
 
Yeah well.....lol That looks good! Is that on the orange car? You ever gonna finish that thing?

Yes the Orange Bomb. I hope to get an engine back in and finished up to run/drive. Things are looking a bit better recently.
 
Harbor Freight has a bender for 1/2", and just googled , there's a 5/8" bender out there too. I do not know what the bend radius is.
 
Looks like Ridged does make a 37° flaring tool for AN fittings. Just so those who don't know , they are different. This is mine.

Swagelok is the bee's knees, I got very familiar with their fittings working on my research project in grad school (sub-ppm gas contaminant blending system) and really wanted to use it on my car projects but had a hard time finding retail outlets, seems like they try to only sell to research or industrial customers. Where did you get your bender from and did they sell fittings too?
