I have a hand held sampling pump but in retrospect should have gotten a one handed brake bleeder vacuum pump instead.
Can use that for other things more comfortably eg brake bleeding, drain and fills of power steering reservoir, brake fluid reservoir etc.
You want the type where the tube is removable and doesn't touch anything ie just like the oil sampling pump.
It ain't what you don't know that gets you into trouble. It's what you know for sure that ain't so.
