Pump normally goes all the time if it is drawing air . Dont know the set up on that car , but you usually have at least vent for filler pipe and also a return feed to tank . Have you tested pump is lifting fuel o.k ?

dont understand your problem what do you mean the pump runs contiually its supposed to run if the car is running, do you mean it runs when the car is turned off? does the car still start and run properly?
