I am surprised that thepumpguysc's posts did not include his baby powder trick:
Wash and clean the pump and surroundings thoroughly.
Spray the pump with brake cleaner and blow it dry.
Cover the entire pump in baby powder (talcum powder).
Now you can observe where the pump leaks, use a mirror to check the back of it.
