I don't know how the vacuum pump works, but if it has a diaphragm in it that can malfunction, how does the oil travel
away from the vacuum pump when air normally travels toward the pump?
If the diaphragm you're talking about is the fuel shutoff valve, then a filter between the shut off valve and the key switch would be a good idea.
If you're trying to protect the pump from dust, then a filter at each branch would be needed, but how often to vacuum pumps fail?
