Charcoal Canister Install

[Strike2]

I'm getting ready to plumb my F150 charcoal canister to my 96 explorer upper. My EFI tank has a threaded check valve so my plan is to run hardline along with some fuel hose to the canister small port. My question is where is the "best" place to install the other line I understand that it needs some sort of vacuum? and is the other port the one I need to use? it looks like some Bronco owners are capping the larger of the 2 ports and removing one of the mushroom caps. I'm so confused

If anyone has a picture of there set up it or a link that would be helpful.

Thanks and be safe !

The two mushroom caps are simply vents.

Vent line from tank into small port as you are planning.

The other small port can be used to route the filtered fumes over to the air intake tube, preferably in front of the mass air sensor.

Some people also use an inline electronic purge valve on this hose so it only opens when commanded by ECC.

Thanks Rox Crusher!
That’s one less item on the to do list
