I use the Mityvac Evacuator everyday at work, I am a Ford Diesel Mechanic and this is a vital tool. Most guys in the shop have the earlier model and it leaks at the pump portion after about a year of use. The 7201 has the pump externally mounted so there isnt any fluidcontamination of the seals. Also, it has a bigger tank and is way faster than the earlier models. I got this from Amazon for 1/3 the price of what the tool trucks are advertising. Highly recommend this product.
