Gasoline leak after sitting

[ExTex]

During the winter, when I let the bike (1988 Hawk GT) sit a while and the float bowls dry out, I have a fuel leak which seems to be above the carbs.
The parts drawing seems to show a simple plastic tee and rubber hoses. Am I correct ? Could the leak be there ?

And why does the leaking stop after a day or 2 of having gasoline in the float bowls and the gas lines?

Any ideas will help.

Thanks

the float bowl gaskets may shrink while they're dry but swell up and seal again after a day or two of exposure to fuel. i've seen it many times. heat also swells the rubber, so getting it running for a few minutes will speed the process, but have a fire extinguisher standing by just in case.

What Jerry said,

But also, its probably not a terrible idea to give the fuel system a refresh. New lines, new bowl gaskets.

The problem likely will only get worse with time.

Can the float bowl gaskets be changed without removing the carbs from the bike ?

I'm planning to change these fuel lines and replace the bowl gaskets. I might as well change to pods at that time.

After a search of the forum, it looks like 7.5mm id tubing will work. I'll try to order some.

Thanks
