I recently bought the automatic compressor drain kit that Harbor
Freight sells. It consists of a petcock that gets inserted into the
bottom of the compressor; some sort of chunky fitting that goes into
other end of the petcock; a good bit of small diameter hose; and a
The directions are typical of HF products. They don't explain what
things are for or whether they are optional or not.
I have installed the petcock, the chunky fitting, and a small portion
of the hose (it's laying on the floor of the garage). The directions
say that the hose is supposed to go up to the air-intake where the
T-fitting comes into play.
My question is: will this product work without that loop up to the
air intake? I bought this item because I didn't want to have to tip
the compressor over every time I needed to drain it. I'd much prefer
that it did the draining on it's own.
