Accelerating Pump Assembly

Check the pump operation as follows: Pour clean gasoline in float bowl (1/2" deep). then operate pump plunger several times to fill cylinder and remove all air from discharge passage. Use a small brass rod to hold discharge ball down on its seat, and press pump plunger down. No fuel should be emitted at either the discharge or intake passages. If fuel discharge is noted, remove check balls and inspect for damage. Reset ball by using a small brass rod on ball and tapping lightly to form a new ball seat.
