I got some clear vinyl tubes and it says the tubes can be used for chemicals, gases (like air), and greases but can it withstand gasoline? Will it be alright to used it to connect gas tank to the carburetor?

No - unless specially made for this purpose do not use plain ordinary vinyl tubing for gasoline and other hydrocarbons. It is not clear from your description if it is made for the job or not - does it say anything about petroleum products? Does it have any maker's name or product number?
 
In general, it needs to be a cross-linked polymer to work with fuel. The only non-cross linked material that comes quickly to mind and is fuel resistant is poly vinyl alchohol...and that dissolves in water. Only use hose which is fuel rated.
