Chevy & GMC Vans

I finally got some cash to work on the van. It's been missing off and on, there's been a loss of power, etc.

I pulled the doghouse and found a whole bunch of rotted vacuum lines.




That part of the splitter that points downward is completely gone. I have no idea where it goes.

Can somebody shed some light on this? What is the thing in the first pic? Where do these lines go?

At least hook me up with a vacuum line diagram; I've never had much luck finding those...

If you get any info on this let me know as well!

Looks like one of the two 'T's in the bottom left of the diagram.

TB, Thanks so much for the diagram! Been chasing an issue FAR TOO LONG and with this and my stupidity, think I'll tear all mine out and swap in all new ones. Kelly

Glad I could help.

I got mine fixed as well... I did find some diagrams, but I forgot to post that and upload them.
