IMO You probably still got air trapped in the fuel lines from the tank through the fuel pump to the carb. when I run mine out of gas it is a royal pain to get started. I have to spray carb. cleaner down the carb. work the throttle up and down, I try to spray carb. cleaner down the carb., but don't recommend this if you don't understand mechanic's to keep it runnig long enough to let the vacuum fuel pump work all the air out of the fuel lines, pump and carb.

even after you get it running on gas again it may surge up and down for a few min. till the lines get the air out.

to get it going quicker you may have to remove the fuel ling from the pump lower it and let gas to start to flow and connect it. I've even gas as far as remove the lines after the fuel pump and pour gas down them. the small vacuum pumps are weak and are hard to get primed IMO.

What's the Sears 917.xxxxxx number, so we can identify WHICH Briggs? Or the Briggs Model & Type#'s.

How many seconds does it run?
Does it have a carb fuel solenoid? If so, is there 12V at it when the key is in the RUN position?

There is vacuum going into the fuel pump but nothing comming out the gas line??

Vacuum going to pump?? should be fuel??? Again IMO air trapped the fuel line or pump is not being pulled up to the carb. You've lost the siphoning effect now you got to purge the air out. I would also check the vacuum line coming off the cylinder head for cracks, not likely beings it was running fine before. IMO you will have to prime it several times to give it a chance to clean the air trapped in the fuel inlet system.

Outside chance the fuel pump maybe bad, but I would make several attempt to prime it before I started buying parts.

Another thing if one line had a hole in it the others are probably bad or ready to go also not knowing how old the LT is caused you never mentioned it???

If it is several years old You might as well change all the fuel lines from the tank to the carb. Or you maybe chasing this problem all summer not to mention the fire hazzard if the lines fail wher hot parts are. You will probably be suprised what you find.

Replaced the whole fuel line! The Vacuum from the carb is working ok! No suction from fuel pump! Took whole pump a part and looks fine. Like I mention on my firist post would start but not keep running. Sprayed carb cleaner in the carb. How would I go about priming the fuel pump. The only whole in it is for the fuel line. It is on the side. Will keep trying!! thanks for all your help

In the unlikely event this happens, I just remove the gas tank cap, press my mouth against the filler opening and blow. (Don't inhale!)

Fill it up with fuel along with the hose going from the fuel pump to the carb. You need to try the carb. cleaner several times with throttle at least 3/4 up to see if you can get enough RPMs out of the engine to start the fuel flow through the pump siphon the gas through.

If you have and air compressor adjust the pressure down low as you can get it say 5 PSI stick a rubber hose on the blow nozzle wrap a good size rag around the fuel tank fill cap opening, stick the rubber hose in and apply pressure if you don't want to use your mouth. pull the hose off at the carb and see if the gas starts flowing.

Now all you would have to do it get the gas through the carb. which carb. cleaner priming should alow the engine to fill the little carb. bowl and it to start flowing, If not I would start guesing, the fuel pump would be the first guess. Again you never said how old the LT is????? Again without knowing what you got we are gussing? well, were guessing anyway!!!!???

Most LT fuel setups are fuel tank under the seat( is yours??) fuel hose from tank to filter, fuel hose from filter to pump, vacuum hose to operate pump, fuel hose from pump to carb.?? If you mode has the tank mounted in front of the dash above the engine then gas should be flowing like water running down hill!!
