The larger line from the tank goes to one of the primer bulb leads and the same size line goes from the primer to the carb. The smaller line goes from the small outlet on the carb to the tank.
Hook it up and try the primer. if it does not fill up then switch the position of the lines on the primer.
I just had the same model that would not prime and had to rebuild the carb. If your handy it is not very difficult.
take the carb off and take it with you to the local lawnmower repair shop. Ask for a rebuild kit.
Only remove one side at a time and be carfull there is a sprin under the needle jet that is not in the kit. replace the diaphrams on both sides of the carb and the gaskets. Match each up as you tak them off and be carfull to put them back the same way. As you go spray carburator cleaner through all the holes in the carb to make sure they are clear of gas residu.
Also in addition to the diaphrams on either side ofthe carb also replace take out the needle jet that is held in by the spring and leaver and make sure the inlet is clean.
Also carfull remove the screen. It coms out with a slight pulling motion and carfully push the new one in.
Again make sure all the ports or hols are cleaned out with carb cleaner.
Wear safety glasses when spraying the carb cleaner and use the little tube that come on the can!!!
Do not turn any of the air mixture screws. If you did have it adjusted by and expert or after all the work you will burn up the motor.
