1974 450 SEL Vacuum Door Locks

Seems like the vacuum locking system has lost its get up and go. Can anyone tell me how to either pump up the vacuum pressure to the door locks or-probably what I will end up doing-DISABLE the vacuum door locking system? Thanks.

check fuse, check pump check line, these are the possible places of defect.
