I'm guessing no, but if anyone is to help, they need to know if you ever plan to smog it or use the stock computer. I'm pretty sure both the map sensor and purge solenoid will throw check engine lights with stock ecu as well as failing visual.

if you're not concerned with emissions, MOST of that crap can be deleted.

I don't actually see that many vacuum lines in what you circled. The stuff on the right are mostly fuel vapor lines for your evaporative emissions controls. A lot of people have eliminated their charcoal cannister (including me). But I wouldn't have bothered if I didn't want to use that space for a WI pump.

once you disconnect the 2 or 3 lines teed off the 2 sensors going to the mani, you can pretty much remove a majority of that clump. then figure out your charcoal cannister delete and you're set
