it takes a good compressor to run that thing.


I ended up buying a $30, 2gallon compressor from HD.

Then on the intake side of the head where it pumps in air to the compressor, i used epoxy to mount a Brass Top Can Tap 1/4”, over the intake port, and bam my own lil vacuum pump, with this and a set of gauges you can do your own a/c ..

+1. A poopy little compressor just doesn't do the job.
