I strongly suggest that you use a "clean as new" one. For the small price of a new Pump Oil Can it's not worth contamination of your brake system. If you have an old one that works well but has oil in it, solvent wash followed by spray brake cleaner, followed by compressed air should put in to work for you.
The old Pump Cans were built well. I've picked up some at yard sales that are likely 100 yrs old and still pump just fine. Ahhhh.. the good old days when "Made in America" actually ment "Quality".
