99 burb vacuum line diagram

[whytry]

hey all, recently did a motor replacement and a couple of the vacuum lines are broken and I'm sure the ones that are brittle are leaking. Is there anyone who has as diagram of where the line go and what goes where etc? I have atleast one that is broken and I'm not thinking some of these connect to each other and want to be sure.

Truck runs strong, but after about 10 miles I get the random misfire code typically 304. Changed plugs, cap n rotor as well when did motor swap. So pretty sure it's a vacuum line leak.

Thanks!!

There really aren't many. There are the emission related ones on the routing diagram...

And one that connects on the driver side and runs over the intake to the solenoid on the heater hose valve. A rubber vacuum hose then goes to the heater valve.
