Well.....it doesn't technically require that the CAT be removed to pull off the air pump. The air pump is there to raise the CAT temp quicker upon start up for emission purposes. OP should do some searching and reading!
I'm more concerned in that you think you can just start pulling off random vacuum hoses in the engine bay without suffering any ill effects.

1. Removing the air pump is possible. However, there is a component that is needed in order to run the fuel pump.
2. Take some time to research your vacuum lines... trial and error is not a good way to check vacuum lines. Do you know what the VFAD is? And there are three vac lines on the back of the oil filler neck. 2 are very important... one, not so much.
Dig a little deeper, you'll understand what you are trying to do a bit deeper than simply clean up your engine bay.

The connection that broke that you speak of....................It actual could cause some idling issues.
Concerning only this hose.......What I would do is.
A.) Go buy the plastic elbow and fix it.
B.) Install a catch can, which would then mean the hose from the oil filler tube would run to the catch can and therefore prevent any oil from running into the intake from blow back or overfilling and prevent gunking up the intake, and MAF.
Search on "catch can", a lot of us do this.
The output of the catch can would then either be vented to the engine bay(and that input on the intake plugged), or the output of the catch can would run back to that very input on the intake.
The problem with just capping it now is, you still have that hose on the filler neck, and any oil that comes out of there is going to get spewed everywhere in the engine bay if you just let it dangle.
Not sure you wanna go the catch can route since you are looking to eliminate them, or at least cleaning up the engine bay, but I think you should consider it.
Just read Vyn's response...........he's right......there is something related to the air pump that must stay as the fuel pump uses it. I think it's a valve/switch, you'd have to search.
On the oil filler neck, I'm assuming that we are talking about the one near the oil filler cap and that runs right over to the intake and not elsewhere.

Thanks ^^^^^ this just came to me because recently i had taken everything apart in my engine bay..
Intake box/battery/Radiator/ removed vacume hoses from the stock air box
But when i put everything back.... i had an issue with my idle......it ran smooth up to 9k rpm..but at 800-900 rpm.there would be this vibration,,,
which led me to believe that i probably didnt connect my vacume hoses on right....
i dont think it could be my motor mounts because i replaced them 200 miles ago...and it was running super smooth before my coils and spark plugs went bad..and Broke my radiator at the same time LOL

Was helping a girl with her car and that same plastic elbow was broken. It did affect the idle. Went and got a replacement and it idled fine after that.
It's not the only cause, but it is certainly one.
