stalls when stoping, only when gas under 1/2

I have a 1990 accord with 300,000+ When ever the gas gage gets bellow 1/2 it stalls when comming to a stop or turning a corner. I replaced the fuel filter, plugs, air cleaner. Is there a fuel pump in the tank that could be weak.

For the Accords, the fuel pump is normally towards the rear of the car on the drivers side. it's normally right in front of the rear drivers side tire. With the car running you can sometimes hear it if you put your ear close to that area.

Probably check the PCV valve and other vacuum hoses under the hood. Also, make sure the car isn't idled too low
