If you have a typical compressor, don't get the El Cheapo from Harbor Freight!
I got one, but it doesn't work. Several problems with it:
1. The way it senses pressure is right off the compressor head. So since the
air is hot, it will melt the plastic line they provide. Which is how the
instructions say to plumb it.
2. It fired backwards. I don't remember why, but when my tank was charged,
it would dump. But it doesn't shut off until the pressure is releived
or something and drains the tank.
I'd love to find a nice inexpensive one.
