B3.9 and B5.9 Series Engines
Cold Start Timing Advance System (KSB) Pump Mounted (005-070)
Section 5 - Fuel System - Group 05
The early pump-mounted KSB is a different design using
two control lines. The two-line version was superseded in
mid-1988 with a one-control-line version, which is the de-
sign used for both production and service at the moment.
There is no remote-mounted hardware available for the
two-control-line KSB, so they can not be remote mounted.
