Help: fuel coming out of drain/ vent hose

[New2gs500]

New guy here who inherited a bike with a rusted fuel tank after sitting outside for 5+ years.

I purchased a new tank and installed all hoses, bushings and mounting brackets in the same configuration as the old tank.
Everything looked ok so I put in aprox. a quarter gallon of fuel. There were no initial leaks so I thought I'd take a shot at starting it as it did run prior to sitting.

After quite a bit of cranking and twisting... nothing and then the battery died.  While putting on a slow charger/ maintainer, I noticed a slow but steady stream of fuel coming from one of 3 drain/ vent hoses below the engine.   After a few minutes, the stream stopped being steady and came out in waves.  Then it stopped completely.  I can't determine exactly where the hose starts.

Does anyone have any ideas?

Did I just flood it by cranking & twisting too much?
Did I connect something wrong (everything matched as it was with the original tank)?

other?

The first thing you need to do is figure out what hose it is coming from.

That should get you started.

floats are sticking.............what position is the petcock in?

If the hoses are routed correctly my money would be on a stuck float or a bad needle seat in the carbs.

shonole,

from this diagram and as far as I can follow the hose, it seems to be the airbox drain hose.

this could be stuck floats.  I have it on PRI before and during cranking/ twisting?

Should I wait until morning when the battery is recharged and all fuel would have drained/ evaporated and try restarting?

If it happens again, I would assume it's the floats and would need to somehow get the bike to a shop.

I'm with Balt on this one.  Stuck float or maybe the needle seat.  You installed the new tank, no?  Then you should be able to get to the carbs.  It seems like a daunting task, but it's really not that bad at all.  Invest in some japanese standard screwdrivers, or be prepared to replace the screws with hex heads. 

In a pinch, try tapping on the side of the float bowls to see if you can unseat them, then see if it will fire.  Although, if it's been sitting for 5+ years with a rusty tank, the carbs are definitely going to need to be cleaned.

Well 24 hours later and there's no sign of a leak.  Tried again to start it this time with the peacock set to "on".  No more gas coming from the airbox drain.  Then again, it's not really cranking either.  The starter sounds like it wants to turn over, then doesn't.

At this point I Think I'm just going to somehow get it to the shop.  It would need to go there anyway as I'll still need to do a ton to get it roadworthy including:  starter motor checked and replaced if necessary, carbs cleaned, fuel and vacuum hoses inspected and replaced if needed, fork and cables lubricated, bearings checked, chain inspected and replaced it it's deemed too rusty, front tire checked as it has a slow leak, etc...

Given I'm a complete newbie to this and my life may well depend on the work, I would feel more comfortable having the pros get it to a solid base.  From there I could do maintenance and upkeep.  Anyone have any idea how much this might cost me?

In the mean time, I'm signing up for a beginners rider course which should get me on the way to a license.  At 47 years old, I hope it won't be too challenging.

Once done, it's another big item off my bucket list      (already checked off are bungee jumping, sky diving, getting on a race track, living abroad, and a few other experiences I dare not mention here  

I'll keep you posted.
