The Story
The P7100 injection pump uses an AFC housing assembly to control maximum fuel delivery under low boost conditions. This housing has several adjustments, one of which is its position frontward-rearward on the governor part of the pump. When installing the BD-Power kit, the AFC housing is moved all the way forward. This adjustment minimizes the fuel hold back from the AFC link at low boost and also allows the governor rocker to move farther forward along the fuel plate. This forward movement of the rocker corresponds to greater rack travel and more fuel delivery.
