Default Leak from carburetor fuel input?

Hey there fellas, going to hop on my bike this morning and I noticed a huge pile of fuel underneath. Probably from the huge temperature spike where I live, but anyways I did some digging underneath the tank and found a pretty steady leak coming from the carburetor/fuel connector. I'll see if I can post some pictures of where I am almost certain the leak is coming from, just wondering if anyone has had this issue before and done a fix on it? Any info on this would be great! Thanks.

The bike is a 1998 CBR 600 f3. Not 100% sure if it is the SJ edition or if it just has the paint job, irrelevant information i believe.

weak screw clamp? try propping the fuel tank up on a 2x4 with everything attached to isolate exactly where the leak is coming from

It's a good idea to turn the fuel valve to the off position when you park it. This was required on old school thumpers if you didn't want to come out to a flooded bike. Modern bikes have better fuel flow control but it will save you a headache if you shut it off.

Even better is to run it for a few after the valve is off. And if it will be parked for weeks or months, of course run it out of gas.

what I found was the tubes attached to the carbs were damaged. (Non-heated garage) Take apart the bike down to the carbs and check to see if there are any cracks in the rubber tubing. I had to replace a couple of the clamps from the 2 finger grip thingys to the metal clamp tightened by a phillips. Seemed to do the trick.

The plastic T's have o-rings on the ends that shrink and crack over time.

I'm replacing all my orings. They are more like plastic than rubber. I can actually see on one I ring where the gas was passing.

Great post, seams common from the feedback I've received.

Now I got to find them outside the dealer.
