Remove the power brake booster hose from the plenum and the vacuum hose between the fuel pressure regulator and plenum. The ports are on top of each other on the back, driver side of plenum.
Remove the vacuum hoses from the mid-plenum: left and right. Remove the vacuum hose between the MAP sensor and the plenum. I disconnected the electrical connector and took the whole MAP sensor off, it's only held on w/ 2-T27 screws, it's attached to the back of the plenum. Made it easier for me at least.
Open the gas tank cap and connect a fuel pressure gauge(w/ a bleed valve) to the fuel rail port on the passenger side. Relieve the pressure in the fuel rail to a suitable container. Remove the 3- T40 from the fuel lines. I had to this because one the plenum screws is blocked by these lines and I found it easier to leave the fuel rail on the ground later. There'll be gas left, so have a rag ready.
