pump housing to clear the transducer.
7. Slide the pump block and piston rod forward until the
piston rod is out of the T-slot on the slider assembly.
8. Carefully pull the transducer wire out of the pump housing
until the connection to the transducer jumper is exposed.
Unplug the wire from the transducer jumper (refer to
the electrical schematic in the Parts List section of this
manual).
9. Using a wrench, remove the transducer assembly from the
pump block.
