Boy that is odd... is anyone else having that issue? I tested them both, from your post. If your scroll your cursor over the link, what appears at the bottom of the page?

Oh, boy, you may have just killed it for me. I only have a pancake compressor. What if I drain it and then let the motor run? Will it hold vacuum while the motor drops the pressure?

@Bruce In Philly it’s my end. Not sure why but I’m getting 502 and 520 errors from RL’s site.

It’s me. It’s not you.

1,000 apologies.

Bruce, you can try it but I honestly don't think it could generate enough vacuum to get the gauge into the green. I don't think it's so much the capacity of the pancake compressor that is the issue, it's the fact that the compressor motor on those just doesn't move much air and you need a certain amount of airflow to generate the required vacuum using the venturi-effect of the coolant lift pump. The minimum compressor specs required by the coolant lift tool are 90 psi @ 4.2 cfm. Check your pancake compressor and see but my guess is the specs are lower than that.

I have this compressor:

For $150, it will run air tools, coolant lift pumps, etc. It's not huge and doesn't take up much space. I miss my big 60 gallon 2-stage compressor but just don't have room for it in my current garage. This $150 compressor is great - I store it in a closet in the house and wheel it out to the garage on an as-needed basis.
