Fuel tank solenoid problem..... please help
so i damaged my tank and had to paint it. i'm think i attatched the hoses in the wrong place though. The solenoid that is attatched under my tank does anyone have a diagram for the hose placement?

The fuel lines should be oblivious and the vacuum line goes to the horizontal fitting not the one pointing straight down.

ok the one pointing straight down had gas pouring out of it when i was pouring gas into it today, but i have no other hoses to connect to it. should i just put a rubber cap on it or do i have the wrong hose on it. the bike also doesnt want to start so i assumed i have to have a hose messed up somewhere

as you can see in pics.the nipple that goes straight down,does not have a hose connected to it at all.
on the very back where the nipple is to the side is supposed to have a vaccum hose connected to it.
if there is gas coming out of the bottom nipple,you need to buy a rebuild kit.it is leaking and is not good.it can leak into the motor and exaust.
geekonamotorcycle went thru this.no choice but to get a petcock rebuild kit if it is leaking thru the bottom nipple.
i beleive the nipple on the back,facing to the side is called the pvlir.

there is a line that comes from under your carb on the rear cylinder, that goes to the petcock on the back side and it points to the left side of the bike. if you cap the line you will never get your bike started.... also if it leaks like that then a new petcock is in order, it is not supposed to do that......

If it is leaking fuel it will not work no matter how you hook it up. The diaphragm is damaged\torn so no matter what you do it won't open and it will continue to leak until you repair it or the bike bursts into flames....
So it just fix the problem before you have a much bigger problem on your hand.

There are a total of 3 hoses connected to the petcock. one to the back which connects to the crankcase and one to each carb. I am not 100% certain but I believe those two are interchangeable. In the video you can see the straw running out of the nipple that should have nothing connected to it at all. the line that runs from the crankcase should be connected like in this video

If any of them are leaking you need to stop! you don't want a burning bike. Which looks like this:

Not a fuel leak, but you don't want to be happily ridding around when something similar happens.

Yah dont get those confused, they are overfill drains. The one you want runs into the crankcase so follow it down. It uses vacuum from the crancase to actuate the valve in the petcock. If its not on properly the bike might sputter for a sec then die.
Interestingly; in my particular case I ran the bike for 1k with the vacuum line connected to that nipple at the bottom(the dealer did this not I). Petcocks can be funny like that and It has had some bad consequences.

Dude! Ok, that petcock... it should not ever have fuel coming from it unless the engine is running. Get that fixed first like others have said before you try to evaluate which hoses go where. It is operated by a vacuum, which only occurs when the motor is turning over... that's all. Get a rebuild kit (or a new petcock) and rebuild the thing.
OK, after all that is done, You should have a total of 5 hoses coming from the tank.
Two are fuel, and as hawk said, are pretty obvious on their location on the petcock. They come from the carbs, one per side. Then you have a long skinny one coming from your rear cylinder. This is the vacuum line, and when you petcock is operating correctly it opens the petcock diaphragm when the motor is running.
The last two just plug into the bottom rear of the tank and go down into the motorcycle and eventually to nowhere- they are vent/overflow hoses and shouldn't cause any immediate issues with running if they are hooked up incorrectly.

so i switched the hoses. bike runs great now!!! But then i went and dumped gas in it and it leaked???? it only leaks when i dump gas in it and the bike is turned off. it only leaks for a few seconds and maybe 1/2 a pint so its not much but what is causing this. Is that really a petcock problem if it only leaks for a bit when i'm filling the tank?

As others have said, the petcock needs to be rebuilt. It is really no big deal.
This should be the part number from Honda:
16953-ML0-014
I would not trust a bike leaking gas in any amount. They're not supposed to!

A guy I taught a tune-up class with 25 years ago was in his front yard in Huntington Beach on a Saturday morning when he heard an explosion down the street. He and other neighbors ran down the street to find the garage door of a house blown out onto the driveway, and a 16 year old kid staggering out of the garage with his clothes in tatters, like in a cartoon.
He had drained a little gas from the tank, put it into a pan, and started cleaning his dirt bike carb. Water heater nearby.....
Respect gasoline.

I'm convinced that the petcock doesn't use basic laws of nature 
. Mine needed rebuilt a little bit back; it leaked out the bottom, but not while the bike was on or while it was sitting in the driveway. Only when I lifted the tank it would, or weirdly when I put the tank upside down in the sun. The air expanded and pushed petrol out like a little fountain... it was the weirdest thing. Anyway, a rebuild made it function as it should...
