Removing Vacuum Hoses (N/A)
No A/C, no P/S, no ACV, TB Mod. Wired open VDI & 5/6th ports. (89' GTU, if you couldn't tell with the VDI)
What Vacuum lines do I need?
Also... what's the "Vacuum Spider"??

Technically, you dont' need almost any of them 
However, it depends on what you're willing to deal with.
Fuel Pressure regulator solenoid needs vacuum lines, one to a vac source and one to the regulator on the fuel line. However, if you don't run a line and just cap it at the regulator, you get full pressure, all the time. Not so good for mileage, but if you're in a racecar, who cares
Obviously, with wired open VDI and 6 ports, you don't need those vac lines.
The other two are smog related, don't need those either.
The spider isn't quite the same thing in an 89. The 88 had a plastic air port thing that distributed air to each of the injectors. The 89-91s have a metal tube that serves the same function, with small rubber lines to each oil injector. Need those still.
other than that, the only other line you have to have is the one to the pressure sensor on the pass shock tower.
