Help with HF automatic compressor drain kit

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 small T-fitting.
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.
Any tips?

IIRC that length of hose that goes to your smaller "pressure release" line is what signals the drain to open and close automatically when the compressor cycles on and off.

I bought and installed the kit recently. It was as easy as could be on my compressor. I don't have an unloader on my compressor. I have a ball valve in the outlet pipe of the compressor. I turn it off when I don't need the shop pipes pressurized. I put a tee in the line after the valve and connected the small line that goes to the drain valve to it. When I open the ball valve, the drain valve opens for a second and drains the condensation. When pressure in the shop pipes drops, the drain valve opens again for a second. It works like a charm.
Hope this helps.
