Installed the AirFlow Performance throttle body. Took such a long time because I wanted to read and understand the voluminous manual that came with it. Afterwards, spent some time trying to determine the best place to mount the fuel flow sender. Looks like I will need to purchase some new lines to do that, so holding off for now. Also, this throttle body's fuel intake port is in a different place than the one Van's used for designing their FWF kit. The implication is that I think I will need a different line between the engine fuel pump and the fuel intake.
