Can you use regular Russell or Aeroquip AN fittings with aluminum fuel line? Or are those fittings just for braided stainless? Jeg's has 25 feet of 5/8 aluminum line for like $30, whereas 20ft of braided is $117...

Yes, they make an end for the aluminum line called a "tube nut" that puts an AN style end on the hard line. You need the tube nut and a sleeve for wherever you want to put ends on it. About $8-10 for two nuts and two sleeves. Russell also makes a hard tube adapter that uses a compression fitting.

BTW, just finished plumbing my dragster w braided line. I had some of each of three brands, some re-used fittings, some new, but I put all new lines. Fuel, fuel return, radiator, remote oil filter, transmision cooler.

If you use AN fittings buy Aeroquip. It was by far easier to use. If you've never used braided stainless it can be a pain in the *ss to assemble. The Aeroquip went together easier than the Russell or Earls. Earls was the worst.

Cool. I figured since both lines will flow fuel equally, why not go with the aluminum & save a few bucks.

I went with Alum line to save money.I worry about it breaking all the time.I wish I would have paid the money and got hard line or braided steel line.The Aluminum line is real easy to work with.But it has a real thin wall,and breaks easy.
If you go with the Aluminum make sure you tie it down good.So it moves as little as possible.Aluminum line is sensitive to vibration too.

Just my opinion.

That's usually a good idea from the fuel cell to the pump, especially if it is in the rear of the car. I used all braided but my cell is less than 12" from the pump. However from the pump to the carb/ injection, I would use the braided. Jus my .02. I just got through running all the fuel lines for the HAT. I had to go up from a No. 8 AN to a No. 10 AN from the cell to the fuel pump inlet. I used a No. 1 pump from DSRacing in Indy. Darrel Saucier Racing. He flows mechanical fuel injections, sells them, builds his own pumps and throttle body type injections similar to the ROn's terminator BUT with a much better idle circuit. If I wasn't running the hat, I'd be running one of Darrel's TB's. He has good prices on Aeroquip fittings, lines, pumps and belts, and any kind of mechanical fuel injection. He has a pretty good flow bench set up too. I'll try to find his web site and post it.

The stainless hard line works well and if you ever want to switch to alcohol you're set.

I wouldn`t worry too much about the aluminum line. I have had the same 1/2" Moroso aluminum fuel line in my Fairmont since I put it in back in 1987. I run it from the cell to the pumps, & then all the way up to the fuel regulators on the inner fender, under the hood. However, on a street car, you will want to watch out for dents from flying rocks.

We used to use Earls due to our association with Holley. Of all the manufacturers it is the least user friendly as David says.
I like in order of preferance
1)XRP line and fittings. Simply the best!
2)Aeroquip, a close second and very high quality. The do not have the high flow fittings that XRP does.
3)Russel, decent product, still difficult to handle.
4) Earls, last resort.
I too had a 1/2 aluminum line on MM and many other cars. They are easy to bend and last forever. After the first stone, rock, cat, or whatever hit and kinked the aluminum line half shut I eliminated it and replaced it with #10 hose. That is the only drawback to using the aluminum line.

Well, all things considered, I guess it will be better to go with braided. One more question. If you have a regulator like this:

What kind of fittings does it use? Just the regular male-to-male AN fittings, or are there special ones?

I cant tell to well from the pic but most pumps fuel regulators and filters use Pipe to AN fittings. That looks like 1/2" NPT to AN. You should check with the papers that came with the regulator

I think aeromotive uses a non-tapered fitting (it isn't NPT) with a rubber o-ring to seal the fitting. That was acrroding to their catalog I picked up over in Atlanta at the world's great Barnett's speed shop show....lmao

The times I have used aluminum fuel line, I used inverted flare fittings and used my flaring tool to put a double flare on the aluminum fuel line. It was a lot cheaper than buying the Earl's or Aeroquip fancy colored fittings.

Definately could be the o ring type, my pump has those on it. where can you buy the non tapered o-ring type fittings?

What do you guys think of this socketlss hose from Aeroquip? http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=4486&prmenbr=361

It is reinforced with a braid, then covered by an "elastomer".

We are sponsored by Aeromotive.
All of their ports require AN thread fittings with O rings. NOT PIPE THREAD!
You can use a tapered AN fitting with an O ring, but the high flow fittings are what they were designed to use.
XRP is the only supplier of high flow AN fittings that I know of.

I am a little confused. Do all AN fittings need an o-ring?

No, to give you a simple answer. Just as the automotive fittings don't either. It comes down to the way the part's threads are machine or an engineer has determined that either pipe threads or o-ring will be the most effective/economical? way of sealing the fitting to the part.

BTW...AN comes from Army-Navy contracts/specs and over the years Air Force also, for the angle of the flare. AN fittings are 37 degrees on the flare verses 45 degrees for automotive. And in most all cases, high pressure for sure, the two won't seal properly if mixed.

where do you find XRP brand? I've been using Aeroquips. I thought all the An manufacturers advertised a more expensive high flow fitting? reason I ask is I am going to order some -10 fittings next week.

I use aluminum hard line on my car.

I used the red anodized stuff on the first fuel pump a long time ago. That stuff was really hard, and hard to work with. It liked to kink and crack. (I forget the name, Earl's maybe)

Next I used the plain aluminum, and it was MUCH easier to bend and work with.

Good Luck!
