Craftsman mower acts like it's starving for gas

I have a Craftsman LT2000 mower. we have changed plugs, filter (gas and air) and the mower still wont run. It turns over but just don't fire. Did put little gas in carb. and it ran a few seconds and cut off. Gas is coming out of the gas line from the filter where it goes into something (sorry can't find what it is called) that screws to side of motor.Took the gas line off coming out out the other side which runs down to carb. no gas came out. It that little thing I don't know the name of has anything to do with the gas? I do know the line that the gas filter is on goes inside of it an another is on the other side that runs to carb. Any ideas?
Thanks
It's a 22 ohv briggs

Kind of sounds like the float needle might be stuck to the seat, inside your carburetor float bowl. Doesn't take much to unstick it. Unscrew the float bowl but be careful not to change the setting on the fuel adjustment if it's like I'm imagining. (the screw w/spring) If the needle is stuck the float bowl will be dry. When you jiggle the float and unstick the needle, fuel should start coming down, at which point you can put the float bowl back on.

Sounds like the fuel pump, go to partsdirect.com and enter the model number, you will find the IPL for your mower. Have a good one. Geo

The fuel pump is the thing you're trying to find a name for.

Craftsman LT200 Lawnmower

After reading your post I hope I can help. That little thing that your fuel line goes into is called the fuel pump. It is a critical part when it comes to delivering fuel from the tank to the carburetor. On the LT 2000 series with a 22hp motor, the fuel pump is non rebuildable. If gas does not squirt out of the carburetor side of the fuel pump when the engine is trying to start, then, the fuel pump is defective and must be replaced. Good news ! It is not a costly item. Hope I was helpful. One other thing to consider as extremely important is: There are three hoses connected to the fuel pump. Be sure to mark each hose prior to removal and install in exactly the same place from where removed. One hose comes from the fuel tank, a second hose connects to the pump and goes to the carburetor, a third hose is a vacumm hose which routes around the front of the motor and connects to the breather.This is for emissions control. Happy DIY. When purchasing the part be sure you have the model number and description of your mower.

The third hose is a vacuum hose, but it is not for emissions, it uses crank case vacuum to operate the diaphragm fuel pump.

Thanks so much going to try again to make sure no gas is coming from the pump to carb. before we go buy it. Glad to know what it is called anyway. Check price and it is not a bad price. I am thankful for the help that anyone has ever giving us. These forums rock. Hugs to all of you. Let you know if this was the problem.

help

Ok had a friend who knew how to do carb. on mower so he rebuild it for us. Cranked fine. The next time he went to crank the mower it wouldn't start unless he poured gas in carb. Sometimes it cranks on it's own and he said it runs link a new mower the next time you got to put gas in carb. to get it to start. Any ideas. The guy that did the carb. has no clue what to look for now.

Sounds like the choke is not adjusted properly.
