avoid generating a spark.
1. Remove the extractable portion of the old pump from the tank as described in Removing the Pump.
2. Remove the old UMP by removing the four bolts holding the discharge head as shown in Figure 29.
3. Rock the unit while pulling away from the discharge head until it is free.

align (see Figure 30).

of the pigtail is seated in the notch of the discharge head.
