Help, I need a vacuum diagram!

Hey all, would anyone happen to have a vacuum diagram for a 1991 D21 with the ka24e? I just recently pulled and put the engine back in and I thought I had the vacuum lines right, but it appears I was wrong. If anyone has a diagram or a link to one I’d greatly appreciate it, thanks in advance.

Hey all, lookin for some help with diagnosing this. I just redid my rear brakes (drums, shoes, wheel cylinder, and hardware) and bled them correctly I believe. The brake pedal will have pressure when the truck isn’t running and doesn’t seem like it’s having trouble, but when I start the truck and press the pedal, it goes straight to the floor with little pressure. I’ve driven it around my driveway a few times thinking it was the abs system maybe having air in it and it’ll stop the truck, but it’s only getting worse and not engaging the brakes after a while. If anyone has any ideas and suggestions I’d greatly appreciate them, thanks in advance.
