I have not had any need to play around with 8s central locking but if it is like C4 A6 pump and IIRC it only sucks vacuum in one direction and there are either 1 hose or going from the pump if everything unlocks together or 2 hoses if you have option to open just boot in which case 2nd hose is a separate for boot. Door/ fuel flap hose then splits and only 1 hose goes to each door only sucking vacuum and never blowing. Lock/unlock is selected by electrical valve in the door lock actuator unit switching which side of actuator the vacuum is being pulled on. Considering that your pump has been replaced it could be the wrong pump for the car where electrical pins for lock/unlock wires going to actuator units have swapped places.
