Nope, one or the other. If using an early 80's canister with no solenoid; then use the LS1 intake mounted solenoid. If using a late 80's or 90's canister with built in solenoid; get rid of the intake mounted solenoid and use the one that is already on the canister.

My car will have a custom fuel cell and an aftermarket pump. I can't picture what this evap crap looks like, and now I'm wondering how I'm going to set my car up... Does anyone have pics showing this stuff?

I think it would be easiest to use what is already on the Blazer. Everything is already in place, so I would study the two systems and then interface the LS1 to the Blazer EVAP system.
