6. Pull the pigtail connector in the discharge head out far enough to see the o-ring in the sidewall of its socket
(see Figure 31). Remove the connector's o-ring from the connector's socket and discard it. Get a 0.551" ID x
0.070'' wide o-ring from the kit and lubricate it with petroleum jelly. Slide the new o-ring over the pigtail
connector and push it in the groove in the wall of the connector's socket. Lubricate the pigtail connector body
with petroleum jelly and push it back into its socket, making sure its index tab is in the socket's notch.
Pigtail female connector/indexing tab is out
of its socket - this is the incorrect position
when attaching the UMP!
7. Lubricate o-ring and pigtail with petroleum jelly.
8. Align the UMP positioning dowel and boss with the proper holes in the discharge head and push the UMP
into position using hand force only. The UMP should be snug against the discharge head prior to installing the
UMP retaining bolts.
NOTICE: Use hand force to put the UMP onto the discharge head. If the UMP does not seat properly, snug
against the discharge head, remove the UMP and correct the problem.
Do not use the bolts to pull the UMP into position. Use the cross pattern to snug and torque bolts. Do not
over torque the bolts. Not following these instructions may cause parts to fail.
9. Install the four UMP retaining bolts and lock washers. Snug and then torque the bolts using a cross pattern
technique. Torque to 7 ft-lb (11 N•m).
10. Replace the packer o-ring and the discharge o-ring seals after lubricating them with petroleum jelly.
11. Reinstall the extractable portion into the tank using the steps previously described under "Installing the Pump"
on page 15.
NOTICE: Before replacing the extractable, make sure that the surfaces of the packer o-ring and the dis-
charge o-ring seals are clean.
12. Refer to section entitled "Testing The Installation" on page 30.
13. If applicable, open the ball valve down line from the pump.
