I gutted my smog pump and all the associated stuff on the passenger fender well and now have a bunch of brittle plastic vacuum lines. I have done some web research and it is unclear what can go and what must stay. I did find that the electrical/vacuum things need to stay hooked up electrical but those lines could go. Thanks for any help. Jim

Did you also remove the check valves and cross over tube from behind the exhaust manifold as well? As far as the vacuum tubing, yes you leave the TAB/TAD/EVR electrically plugged in, but cap the top ports of the TAB/TAD solenoids, shown with red arrows on the left. Run new tubing from top port of EVR (blue arrow) and use "T" fittings to tie in the bottom ports of the TAB/TAD solenoids (other blue arrows), then run that line to your vacuum reservoir (coffee can) and then come out of that into your vacuum tree on the intake manifold. If you deleted the coffee can, simply run the line from your TAB/TAD solenoids straight into your tree. The blue line coming out of the EVR (bigger red arrow) runs to your EGR valve.
I did something similar to what armybrat describes so as not to get a constant MIL. Removed the air pump tubing but left the vacuum reservoir as it is needed by the EGR.

Thanks and sorry it took so long to get back. I have finally come to this project. There are a few i=other lines I have questions about and will take pix tomorrow. For instance the lines that control the heat. Also what is the intake "tree"? Thank you. Jim

It's just a port where your vacuum lines tie in. It's hidden right behind the bracket that is shown on top of your intake manifold in the bottom pic you posted.
