The is the sign of a bad fuel pump, and or air leaks in the line, or a restriction on the fuel tank I would first replace the fuel lines and the primer bulbIf it still does it the fuel pump needs to be rebuilt or replaced, i would change the fuel filter(s) alsoAs you pump the primer your acting like a fuel pump
