The cylinder in the first picture is the "gas filter"; all three nipples are just engine vacuum. Depending on the engine and accessories, they drive cruise control, ADD, Fuel Pressure-up, AC idle-up, and PAIR. On vehicles that don't have one (or more) of those, one of those three nipples might have a purpose-made cap, like muddpigg has. Yours obviously has something that needs that vacuum, and it now has a red-neck bypass.
As to "why" it was bypassed, it depends on what is now missing vacuum.
As muddpigg says, the VSV in the second picture opens to atmosphere, and it came with a filter like the VSV next to it. Without the filter, you could be sucking dust into (for instance) the fuel pressure regulator.

Like Muddpigg says above.
The stock cap on vacuum connector is a simple vinyl cap.
What looks like a cap on the VSV (the black cylinder) is actually a filter so no dust /particulates goes in or out when it back-fills to release vacuum

On the 22R-E, one of the three ports on that vacuum connector is plugged (see port to right and just above the hose-clamp screw). That is stock.
That available port is good to use for a dash-mounted vacuum gage like 4crawler did.

might be redneck, but it doesn't leak.

So I'm gathering that I just need to Capp mine off. I was thinking I could get some more line and connect the two but then like some of you mention(the redneck Capp) is why it doesn't have a Capp. The p/o isn't gonna know as he didn't know much about it before but thanks for the pics and the awesome advice.
