So, I'm trying to temember some things and can't find the answer for. I'm looking for where the hell is it that the bottom hose of the recirc valve goes to, in the pic it is connected to a pipe, but where does the pipe end? is it at the engine block or does it go back the intake or something?. I removed my stock recirc valve and I'm jusr trying to find out how it was put together from stock.
