It seems like I am always having to put a quart of some ATF, power steering, or differential oil into some remote vehicle cavity on a regular basis. Can anybody recommend a convenient hand powered fluid transfer pump that is easily cleaned so that I can change fluids easily? The constant hassle of trying to find something that works for most applications has been driving me nuts for years. So far the best I have done is a nice oil can with a plastic tube. In cleans up easily but it is sloooowwww.... I finally thought I would break down and ask for advice.
