Problems with AN fuel line setup, I have leaks, help please...

[Iron Indian]

Ok guys, here is my setup so far...

-XRP -6 AN Tube Nut + Sleeve (x1)
-XRP -5 AN Tube Nut + Sleeve (x1)
-XRP -6 AN Male to -6 AN Male Union (x1)
-XRP -6 AN Male to -5 AN Male Union (x1)
-XRP -6 AN straight female hose ends to connect the tube under the car (X2)
-XRP -6 AN straight female hose end to connect the lines to my PRJ fuel rails (x1)
-XRP -6 AN Angle 90 Degrees female hose end to connect the lines to my PRJ fuel rails (x1)
-XRP -6 AN Steel braided hosing of course

I installed everything. The hoses went together smoothly, everything bolted to the rails nicely and all. What ain't working is my connections on the factory hard lines under the car. I bought all the above at a local speed shop and got good instructions on how to setup everything. When I put the sleeve and the nut together on the hard line (after cutting it obviously), I flared it with a flaring tool. When I assembled everything I had leaks at the hardline connection! I tried flaring some more, even sanding smooth the bevel and I had leaks on one line constantly. I cut off the flare and tried again, it held. I drove the car a little that night, I got back home and the other line is leaking! There tighter than hell too. I'm thinking these connections ain't worth a damn IMO. I think part of the problem is both tubes on the inside have a seam line and I think the leaks are coming from there. Esentally I can't get a good seal. I don't like it so its time to do something different than this.

What can I use different? I've heard of Swedgelok setup. How can I adapt this to my setup and where can I buy the parts at? I'd appreciate the help. I know the 5/16 side will be a pain to adapt.

I only get one weekend a month off and I wanted to get this littlep project done, thats all. So much for that idea. i'm so pissed on how this turned out. Kinda wishing I stayed with the OEM setup now... Ugh

I know they dont require it, but did you try any type of sealant??

shawn-

Permatex makes an Aviation sealant(WORKS WONDERS) we use some of it at work, so I picked some up at the local O'Reilly's. comes in a white container with a brush in the lid. It is good for all fuels, coolants, other chemicals. I guarantee it will seal anything or I will send you the money for it!!!!

otherwise my other idea is just run the -6 line directly up to your fuel tank. since you have it almost there...just get some more line, and use the quick disconnect to -6 fittings.

could you take some pics? I have the -6 to line fitting already on my S10(LS1)...I havent had a problem.

I got two bottles of it here, but havent found anything to use it on yet but with that kind of good things being said about it I guess I wont have any worries about what I do use it on.

Thanks guys, I think I came up with a solution. It'll be a few days before the parts get here though...
