That is the vacume line for the fuel pump. If its got fuel leaking out I'd say the fuel pump needs chunked or rebuilt.

Absolutely what billy said.the cylinder pumps air to work the diaphram.

How does that little elbow thingy that goes into the cylinder cause the pump to need rebuilding?? That little elbow is loose in the side of the cylinder and is leaking. Is their anyway to tighten it or is it just worn out? What is the name of this part so i can get a new one. Thanks

Its not suppose to have fuel in it, at all, ever. That elbow creates a pressure from the cylinder that operates the fuel pump. If there is fuel leaking out of the elbow, either a line is crossed or the fuel pump is fubar and needs repaired/replaced. I've never had one come loose...but I think its probably just pressed into the cylinder. If thats the case then something must have hit it to knock it loose. Atleast thats what seems logical to me.

Tap it into the cylinder with a. (Lightly, dont whack it!) I just pulled one out of one cylinder and put it into another.
Do NOT reconnect the hose to it!
As others have said, that is a vacuum line that operates the fuel pump. it should NEVER have gas in it. If it does, it means your fuel pump diaphram leaks, and is probably cracked, and its dumping gas right into the bottom of your crank. You will need to take apart the fuel pump, and replace any cracked or leaking components.

Be sure to change your oil when your done with the rebuild.If it sucked gas into the lower end you will wash all the oil down and ruin the motor.
