An 8mm socket was used on the two vacuum block screws on the throttle body. The passenger side vacuum line bracket nut on the doghouse was unscrewed with an extended 13mm socket.

The PCV and vacuum line that bring up the rear of this block must be undone for us to access the fuel rail; both cracked while we were trying to pull them off. They were terminated with extreme prejudice, and replacements were purchased at a GM dealership. Since the rear two lines are connected separately on the block, once the bracket and vacuum line were routed away from the fuel rail the front three lines and the block were angled away without having to remove all of the rubber lines.
