gas leaking

I just had my carbs rebuilt by a professional shop. I didn't even the bike back for one day and its already leaking gas from the tube shown in the pic

Well your pictures aren't very clear, out of focus. But if your talking about the clear line with the white Tee, that looks to be the Fuel line from the fuel tank down to your Carb's. I see there are no clamps on the lines, while sometimes this works fine, It looks like you need some. Get some Spring clamps for your fuel line size, maybe 1/4", and put those on. The only other thing I can think of on these lines would be if they are going to hold up to today"s gas. Ethonal could be causing your lines to get soft, and deteriorate, causing the loose fit at the barbed fittings. Nice having clear line, but some of the lines won't hold up with today's S**t gas.

ok thanks for the advice

The clear fuel lines are crap. They actually harden and crack with age. If you are leaking turn the petcock off each time you park it.
