Okay I just spent alot of money on fuel lines (hard and braided) and a bunch of overpriced -an fittings. I bought SS 1/2 hard line for the center of the car, but now I need to connect the hard line to the -an fitting (so I can then connect my braided line to it). Anyway I thought I could (or can I?) use this fitting
( http://www.jegs.com/webapp/wcs/store...erm=555-110552 )

but now I'm thinking its not that simple. I'm using a mechanical pump so I want have really high pressure. I think I may have wasted some money here.

Please advise

I can't tell exactly what that Jegs fitting is, but this site should help"

Basically you need to put a B-nut and tube sleeve on the hard line then flare it.



Then you need a male-to-male coupler to mate to the braided line:

Joe, is that for SS hard line? So I can't just use the AN to hard line fitting? SUCKS....

summit & jeg's both list a 'hard line adaptor', I think I've seen it at speedway also, Ibelieve it's a 'ferrule' type fitting,

Dave your probably referring to the one I listed above and inquiring about.

obengston,
I went to your link and clicked on the little jpeg of the fitting. This brought up an explanation of how it works, it is a ferrule type compression fitting, and mentions that flaring ALUMINUM tubing will no longer be an issue. I wouldn't use a compression fitting on SS tubing. I'd follow Joes recommendation. If you look closely at the male to male coupling he posted you'll see that it is -8 on one end and -6 on the other.

Those are AN fittings. The ones I showed are stainless. They are also available in aluminum. I think you will want to use the stainless B-nut and sleeve on the stainless tube. The connector can probably be either. The fitting on the braided hose will be aluminum, but could be stainless if you want to keep it all the same material.

I use what you linked all the time, except I use #110551(6AN) or #110553(8AN) because they are male AN and can help by not needing to add a male AN to male AN flare union(like # 110203 for 8AN) to get hooked to the female line fitting like you would with the one you listed(unless the fittings you have for the braid line are male AN?). They work great, and I've never had one leak and they use the same common 1/2" brass ferrule available at a hardware store or plumbing supply, so iI you want to alter you fuel system in the future they can be reused by just getting a new ferrule.

I never bother to flare fuel line anymore, unless it is in a tight fit situation, I just use these fittings. I only flare brake lines now.

If you are going to flare, you have to have a 37° flare tool for the AN stuff, and they can be expensive for a one time user. Not the same flare as typical 45° automotive and plumbing stuff.

Most companies make compression-type fittings that eliminate the need for flaring the hard line. They aren't as reliable as a flare fitting, but buying a 37.5* AN flaring tool isn't cheap. Compression fittings are fine for high pressure fuel lines. All of the ones I know of are designed for aluminum tubing but I don't see why they wouldn't work for SS

Well, you can tell I'm behind the times. I've never even seen one of those before. I've used compression fittings like that, but I don't like them.

[obengston]

Sounds good to me. Has anyone here used them on SS without flaring? And mine is going to be mechanical pump so low pressure.

[ericnova72]

Used them on both steel and aluminum. Aluminum is a little more finicky, if you overtighten the fitting the crush from the ferrule will distort or crack the aluminum line and it will leak, forcing you to cut it shorter and get a new ferrule and try again. Steel is pretty much fool proof, as long as the line isn't deeply scratched or ovalized, and you can't tighten them tight enough on steel to hurt the line.

No problems even on higher pressure fuel injection lines.

[obengston]

Eric,
Thanks. I'm going to do it this way since I have the stuff already purchased.

[2old2fast]

make sure not to bottom out the tubing in the ferrule end of the fitting, you need enough space so the crush sleeve [ferrule] crushes at both end. [I hope you understand this]

Dave thanks for that tip, wow I would have shoved it all the way in. So your saying leave it a little out the tighten the fittings..
