I am thinking about buying a vacuum cooling system filler.The info on it says it needs an 80 to 110 psi air supply to run , no mention of the cfm requirement for the compressor.Any one used one , and know what size compressor you could get away with.

I could think of 1,000 other tools that would be more useful.

Some engines are a pain to refill and bleed.Filling, burping hoses opening bleeders topping up jacking up and what have you.This tool saves all the nonsense,so for me would be a good addition to the tool box.
