Vacuum pump maintenance questions....

Long story short, I used my vacuum pump to apply vacuum to a kerosene line in an urgent/emergency situation. Yes I know it's wrong, but I'd do it again if need be as I really don't use the pump anymore.
Anyway, what's the best course of action to clean/maintain it now, besides obviously changing the oil?
Thanks

Of course, vacuum pumps suck rather than blow stuff into an AC system, check valves have to be clean. Not sure what kind you have, have a dual stage, easy enough to take apart the pump and clean everything.
