An improved vacuum apparatus and method is provided which includes a vacuum body, pump or ejector which produces a plurality of high velocity liquid jet streams of a primary fluid (liquid) such as water discharged into a convergent diffuser to draw a secondary fluid (gas) such as air into a vacuum chamber. The secondary fluid (gas) is entrained within flow spaces formed between the liquid jet streams and is carried through the diffuser by the jet streams. A secondary fluid inlet is operatively connected to an elongate hose which serves as a vacuum line for evacuating, for example, a Mason Jar, a plastic bag, other food storage container, an oil storage or receiving receptacle, or the like. The present invention is especially adapted for use as or in a vacuum seal kit or oil change kit, but not limited thereto.
