I mean, I guess I didnt speak then... at 3 oreillies i been to, its in the isle with dorman help stuff , autobody paint, and it was next to vacuum t's and it was just below eye line(Im 5'7") on shelf. towards an end.
Its in a square box, hanging, gloss black, and the line is in a circle. I got the same stuff the other guy did. I can show yo uteh box

The reason they are different colors are to do with emissions. If you look at your VECI(this is not mine, I just googled it really quick for a 4.9, no idea what yours looks like) you will see it has color coding on it. on mine, since I used black tubing, I made sure to use electrical tape of the corresponding color to keep it straight if I have to ever look at it in the future. where I had red tubing, red tape is on the tubing, where green went(EGR), I used green tape.
Because most of my lines run on the backside of the engine, out of reach and sight, I imagine keeping it straight is a bigger deal generally. When I do it 100%, Im going to run it over the engine or in front somehow, because I have too much trouble reaching that far back.
The last spark plug really sucks too lol
Id really appreciated if the PCV was easier to get to. I have a new grommet, a PCV pushed into it, then a tube off the PCV to a small adapter, which steps up to a larger diameter "PCV" hose which then runs to my vacuum fitting. My original hose was not good. Its not ideal, but it works for now.

Those t's shouldnt be needed. But is that vacuum rated tubing? as in, you wont have a collapse if you run 3 feet, with 90 degree turns? The reason its hard tubing is it can be a small diameter and also turn without kinking or collapsing. The hose looks a little large. I reused the 90 degree elbows (they were okay) I cleaned them up and used a tad silicone grease to push new tubing into them. the tubing I got at oreillies. Black, shiny stuff

NVM, I remember, it was one of my lines leading back to the vacuum canister which was not one of the small ones being discussed

Yeah, I agree with the PCV valve location. I had to take my upper intake plenum off, replace that gasket to be able to replace the grommet, hose and PCV valve a couple weeks ago. What a pain in the a**!

i didn't want to go with more hard line. It costs alot more for 3 feet per roll vs the soft vacuum line. Plus, it gets brittle...just like the original lines. That tubing is vacuum line. 5/32". I got the tees because in that write up on the Bronco forum, it said one would need 2 vacuum tees to do this...
but I mean, is this vacuum hose going to withstand and not kink? If so, all right, your choice. To aid it, you may consider delibertly interupting the hose sections with some of your t's and splices. Give it strength and allow 90 degree bends without kinking

Youre okay on the t thing, I originally didnt realize this was a small block so I was thinking about a i6.

I don't know about the kinking...that wasn't something I had thought about. Maybe need silicone line instead.

Also the longer the hose, the more likely the situation. thats why I said split it up if you can/need, make turns with elbows etc
thatll allow your plan to work and the concerns i bring up to be handled
