The evap system is very simple, it's just a charcoal canister and a vsv. I just removed both and tucked the vapor hose into the inner fender. I do occasionally have a faint fuel smell from the engine compartment after a drive, but doesn't bother me. My canister was clogged and causing tank pressure build up so I just removed it. The main advantage is free space and less parts to fail. The fuel pressure solenoid was removed mainly because I was already removing all the other vsvs between the intake manifold so I pulled it too. All it does is provide atmospheric pressure to the fuel pressure regulator during cranking for slightly higher fuel pressure. I have not noticed any adverse affects since removed. I simply used a short piece of vacuum hose and connected the regulator to the intake manifold vacuum nipple.
