    Could one of the F40 owners check something for me. I may have re-plumbed the air injection incorrectly when I pulled the manifold to clean my fuel injectors. I'm pretty sure I did not touch touch this but need a check if someone has a minute.

    On the air injection system. Depression tank #40, where does the forward hose lead - the throttle body manifold or the solenoid valve. Where does the rearward hose lead - the throttle body manifold or solenoid valve. The one in the 10 o'clock position is not connected. My hoses are connected with the forward hose going to the solenoid valve - not connected like the diagram below shows.

    Also on the solenoid #42, there is a red and yellow wire. Which wire is on the inside (engine side) and which one is on the outside (body side)? Not sure it even makes a difference.

    Appreciate it.
