Got another question for you sir.

I noticed you installed the pressure switch on the tank with a Tee. Did it have to go there, or could it have been installed at the other end of the feed line at the compressor? Does it matter?

Do you have a one way check valve in the line?

I suppose it could go at the compressor as the line pressure should be the same as the tank although I think the closer it is to the storage tank the better.

There is a check valve in the braided line coming off the Viair 480c compressor so the pressure doesn't back feed into the compressor. It was like that from the factory, I didn't have to add one. On that note, don't put the pressure switch upstream of the check valve if your compressor is equipped with one!

Is this considered upstream?

The check valve is on the other side of the tee, at the end of the braided line.
