That little 90 degree 1/4 fitting goes to a hose which goes to my map sensor. I use that big fitting for a vacuum block that takes care of everything else.

 

I found it. It's the Vapor Canister Purge Valve for the gas tank. It connects to the top front of the stock intake.

So, where do you connect it when using Holley intake.

 

When I had the blower setups on my truck, I just stuck a 3/8" hose on the end of the purge valve and ran it to a vac source on the intake. Worked just fine.

 

What did you do with the hose that is coming from the tank to the purge valve?

 

Just drill and tap and put a nipple into the hi ram and run a hose from the purge solenoid to the intake. That's what I did.

 

This will give you a better idea of how it fits... Also you can see where I tapped and plugged into for the fuel pure solenoid and pcv. These pics were taken before I used better hose and ran the solenoid and pcv under the intake so don't mind how ugly they look lol.

 

Just cut it and slide a rubber hose over it and ran it where I needed it to be.

 

Three, is that the mid ram or the hi ram?

 

That's the hi ram

 

Any more pics of that setup, Three 6?
