CAUTION
Most pumps will have a shim between the KSB and the
timing piston. This shim must be reassembled between
the cover plate and the timing piston. If this shim sticks
to the KSB and is installed with the remote-mounting
hardware, it will block the regulating valve drain path
and damage the pump. This damage is usually evi-
denced by a fuel leak.
Both the four-and-six cylinder have the temperature switch
mounted in the intake manifold, as shown.
