Faint fuel smell at rear of rail/near FPR?

Ok as for that little elbow line connecting your rail to the damper - just ditch the whole damper for now and run the line straight to the rail. The damper just takes out some of the "shock" in the fuel system from the injectors opening and closing (and pressure going up and down from the injectors.) You can run without the damper for the time being just to keep the investigation moving along.
And that sucks about the rail mount holes. I did the same thing on mine. Stripped one of the holes out. Instead of tapping/helicoiling it I bought a used manifold off a friend of mine. Got it home and... that one was stripped too! Argh! I just drilled/tapped it for the next size. Works. Though I like the stud idea... might dig out my original manifold and do that.

I think it's all better now... I ran the pump for probably about 20mins once I got the new jumper line installed and the rail bolted down and... no leaks I can find, and I can't find any smell of fuel...
I had my room mate smell it too, and he said he couldn't smell any either... even had another buddy over and asked him to smell it and he says no too.
Ran the car for a while with both of them around and none of us could smell anything.
I guess that means it's all better. I'm pretty happy about that, but I guess I'm kind of expecting the other shoe to fall... I hope it doesn't!
I wish I could point to one thing I did and say, definitively, that it had been the culprit causing the smell... but I can't really. I mean, I replaced the fuel lines (just the rubber, re-used the fittings), pulled all the injectors out of the rail and inspected the o-rings (nothing wrong with any of them), had my rail powder coated while I had it off (spilled fuel destroyed my previous paint job), put it all back together, then the newly-rebuilt jumper line exploded, pulled it all off again and replaced the jumper line with OEM, and put it all back together again... so, it could have been the fuel lines, it could have been that jumper line (I know, this sounds like the obvious answer, but I swear, there was absolutely no smell at or near that line), or maybe an injector o-ring that wasn't seated properly? I don't know... one of the things I did seems to have fixed it...
Maybe it was the neighbor's cat... he stopped running around in the tank... he must have gotten that damn bunny. I told him he could come out now, but he didn't. He's probably sleeping.

Sweet, sweet victory. 
Sometimes (especially with these cars) you just smile and nod and go about your day. Start asking "why" and you just wind up uncovering more problems.

Celebrations are surely in order!
Woo hoo indeed!
Definitely! I can consume hours/days/weeks/years/lifetimes with "tinkering" for no real reason... I have to stop myself, or else life passes by without my knowing. It's kinda why I spent so much time/energy making my underhood look good... these aren't exactly cars you can go too long without opening the hood... I figured that if it looked good under there, I was less likely to find little "projects" every time I check my oil level
Woo hoo indeed!

If your car smells like fuel there is a real risk that it will catch fire and burn to the ground while sitting at a stoplight. If it does not smell like fuel now you should be very happy.
