Mysterious fuel leak

Ok, I have done the simple stuff - I removed the can under the seat, no problems, no pinch in the rerouted hoses. A couple of months afterwards, I fill up the tank, and see a very slow drip............. drip.............. every few minutes from the bottom of the bike. I thought it was fuel expansion from a hot day's ride, but it persisted - through the winter. The petrol smell in my garage is not pleasant. Since the weather's good (GREAT) again, I am riding it often, and it's leaking consistently. BAD - it won't pass inspection this way.
So, smarty me, I RE-connect the charcoal cannister, and it STILL leaks. I have not traced the leak (yet), but any ideas? I plan on lifting the tank to see if there's a leak/crack/split hose, but I'm looking for direction as to what the culprit might be. I have not lifted the tank (ever), and it took 9 months for it to start leaking (and it is still a very slow leak).
Ideas?
Comments?
Flame thrower?

Thanks in advance.

Is the drip coming from a hose or off the frame?

Some people have had leaks from the underside of the tank where the fuel level sensor attaches. If you lift the tank you can see wires going to it on the throttle side of the tank maybe 2/3 of the way to the rear.

Other people have had leaks from the bolt that goes vertically into the bottom of the tank to attach the throttle side spoiler/tank panel (the one you remove to add oil) - perhaps from tightening too much.

Hope this helps some.

CJC - the drip's source was/is indeterminate, but it is dripping off one of the front hoses (not the fuel breather hoses). I need to find the source.

Well, I took off the left side panel & the chin fairing, and I noticed there was residue around the top bolt hole on the left side of the tank (where the side panel bolts on). That doesn't seem right, but it only drips when parked on the side stand. Hmm - overfilled tank syndrome?
The dripping from below is coming off a rubber hose, but not the two that have been rerouted from the cannister - although I tilted the bike over quite a bit & one of those flowed fuel easily - so they are not blocked.
If the vertical bolt (going into the bottom of the tank) can leak, shouldn't it drain the tank when I pull the bolt?
I didn't have time (or daylight) to pull the tank up to check the fuel sensor fitting - that's my next move (thanks CJC).
Speaking of that - any diagrams/directions on tank removal/lifting procedure? I haven't done it yet, and any tricks of the trade would be appreciated. I recall a few owners having issues getting it back on.....
but I'd prefer that problem than dripping gas.

I think the leaking sometimes comes from the where the "nut" for the vertical bolt is fixed into the tank, rather than through the bolt hole itself but I'm not sure. A few people have posted about it.

I had a slight leak from my fuel sensor - just enough to smell it. If I remember right it just needed a new gasket.

My bike sometimes will puke gas if I fill it too much, or if I park it with a pretty full tank in the sun, but that all comes out the overflow hose.

Getting the tank up is easy - just take out the bolt at the front of the tank and lift. I've had mixed results in putting the bolt back in. Sometimes it goes in easy. Other times it is a real bitch. I can't tell what makes the difference. Patient pressure and greasing the threads is the only way I've made it work when it resists. The parts manual has an exploded diagram of the tank and things connected to it, but you won't need it to raise and lower the tank.

Thanks. It seems that the left uppermost side panel threaded hole goes into the overflow space in the tank, so if you overfill the tank, it WILL leak out that bolt hole, beneath the side panels, when parked on the side stand.
The dreaded fuel-expansion-when-parked-in-the-sun happens to the LC8 Adventures, too, many times causing vapor-lock and/or cannister overflow into the air box - but mine leaks when it's 50 degrees in the garage.
I'm putting $ on the sensor gasket - slow enough to not be dangerous, just enough to be annoying & stinking up my garage (where I work on my bicycles/dirt bike/etc).

Mine was too tight, getting pulled when I lifted the tank. Now it's tied to the frame tube with a cable tie to keep a few mm further away from the head.

The culprit has been exposed. The fuel level sensor is the issue, it's running down the wire insulation & making it's way to gravity. I don't see a gasket in the parts diagram, but that doesn't mean there isn't one. I'm guessing I need to drain the tank, pull the sensor (2 bolts), and install a new gasket.
Anyone got part # for it, or should I just silicone that thing down?

I thought my dealer told me there was one when they fixed mine. I'll see if I can find the paperwork (not sure I kept it).
