Why oh why did I install 30 extra fuel leak points?
Okay, in my woes to FIX a gas leak in a rubber hose, I went about installing hard line and braided stainless.
Well now that one leak has turned into 3. Okay, so... all the leaks are on the pressure side. On the hard lines, I installed the nut, sleeve, and flared to the correct 37 degrees. Fittings are "tight" but not tight enough to break things. I tried loosening and retightening and very little change (leaks did get smaller).
So what's the deal here? Am I supposed to loosen/tighten them 100 times to seat them? I read somewhere that mixmatched brands can leak (wtf? aren't they all 37 deg?)
They have to be VERY clean when they are assembled/re-assembled, the flares especially. You can also tighten them quite a bit, they're strong little guys.
If that doesn't work, try replacing the fittings. IF you do this, be sure to replace both surfaces that you're trying to mate together.
I'm scared about overtightening them though. Everywhere I've read that's underlined in bold letters. I think Earl's (or somewhere) said hand tight + 1/3 turn.
I made sure there wasn't anything on the seals (metal flakes or whatever) before assembly.
All of the leaks seem to be coming from the flared tubing ends, but I can't be certain. Fuel just seems to spread all over and I can't figure out which end of the fitting it's coming from. On the most severe, I have the hard tube end, a male-male fitting, and a hose end fitting. For all I know they're probably all leaking.
** upon closer inspection, I think it's the welded seam of the tubing that is causing the problems. Unfortunately the fiero did not come with seamless fuel line. I'll see if I can fix this with a dremel.

Get a bottle of baby powder, and cover the leaky area. This will show you exactly where your getting the leak from. Also leave the key in the on position and you can connect the battery up while your watching the leaky area.

I was going to mention this then I read your post.
Didn't I tell you something before about using DOM and not welded seam lines?
Ain't gonna work...
BTW, how are you using the Fiero return line with AN fittings? I know there are AN -5 out there, but I've only ever found them in steel (and you can't find hose ends..).

I know, but I want to use the stock fiero lines. It's not my fault they're shitty quality. :scratch:
Summit has -5 nuts and sleeves. I'm using those with a -5 to -6 adapter.
I was going to install an lines for my fuel lines this past weekend, but I didnt get as far as you. I was about to put the ends on the hose when I realized that I had female ends for both sides :lamer:
Okay, it only took 3 months. Fuel lines are mostly fixed. I took a dremel to the sealing surface and sanded down the weld seam burr and smoothed it out. Only 1 flare left to go and I'll leak check again.
What sucks is I took off my quarter panels, so it looks too much like ass to be driving it around. Not that it's going to stop me. :thumbleft:
I think my gas is about 8 months old though, so I'll drain it and throw that in the grand prix. bwahaha
