Please help me build an air ride set up

[4DSEVEN]

Okay I have read through several threads and am trying to gather as much info as possible to do my own air ride.

I have a 49 Chev truck with an original frame. Mustang II front end and will be installing a triangulated rear end.

I would like to start buying bits and peices for a bagged set up and need your help / suggestions please.

Tell me what I need in regards to tank size, compressor size, fittimgs etc.

Here's what I am looking at so far.

Tank:

Compressor:

For the tank I don't understand the fittings part and have read that I should go with 3/8 or 1/2". Is this tank 1/2"?

Am I going in the right direction so far??
